LED Dimmer Circuit with LM317

Today in this article we will discuss LED Dimmer Circuit or simple adjustable Voltage regular Circuit with LM317. LM317 was first introduced in 1970 from then until now the I.C is used for small Transformer Based Variable Power supply.

Things needed for the Circuit:

  1. 330 Ohm resistor
  2. LM317
  3. One 12v LED as a Load
    (We will use this LED for LED Dimming Observation.)
  4. A 12V Power Supply.

Circuit Diagram:

Watch The Youtube Video:


How Does it work?

This is a simple circuit with LM317. We use a Potentiometer/ Trimmer for varying the voltage of adjusting pin. It is connected in such a way that if the residence of the potentiometer is increased then the LM317 output voltage decreases. And in a similar way if the resistance decreases then the output voltage from LM317 increases.

Note: I have used a 10k linear potentiometer. If you want to get more accurate output then I will suggest you go for multiturn trimmer or potentiometer. It will give you a great experience.

Simple Touch Sensor

Today in the article I will discuss Simple touch sensor/ Transistor Touch sensitive circuits. Here I will discuss n channel MOSFET touch-sensitive circuits. MOSFET has 3 pins gate drain and source. The point gate is used for turning on and turning off the MOSFET. Basically, we use a PWM signal for controlling the MOSFETs. But here we are using our Hand as a resister which can activate or deactivate the MOSFET.

Needed components for Simple touch sensor:

  1. N-channel enhancement type MOSFET IRFZ44N
  2. 1K resistor Click Here
  3. 1 LED Click Here
  4. 9v Battery Clip Click Here
  5. 9v Battery

Here is the YouTube video from Creative Creator, This will help you with more clarification.

Schematics of the Circuit for Simple touch sensor:

How the simple touch sensor circuit works?

  1. MOSFET has 3 pins gate drain and source. The point gate is used for turning on and turning off the MOSFET. Basically, we use a PWM signal for controlling the MOSFETs. But here we are using our Hand as a resister which can activate or deactivate the MOSFET.
  2.  If we touch the gate Pin and the Vcc then the current flows from our hand to the gate pin. There it suddenly activates the MOSFET. And the current flows from drain to source.
  3. In the MOSFET there is an inbuilt capacitor this took the charge and stores the energy. The current will flow from drain to source as long as capacitor stores energy.
  4.  Now if you touch the gate Pin and the GND Pin then the stored capacitor discharges and the current flow become lower. There will be higher resistance between drain and source.
  5. So, there will be no flow between drain and source.

That is how the circuit works.

Simple LED Blinking Circuit

Let's talk about the LED Blinking Circuit. LED Blinking Circuit is an easy Circuit consists of 3 basic components like 1 Transistor, 3 RGB (Multi-color) LEDs. This is a Basic transistor Circuit. The LEDs are connected in series with the Base of the transistor. When the 12v Vcc is on then the RGB LEDs connected in series changes their color in a systematic way. The changing color triggers the transistors Base. As the Transistor Base Voltage is changing the amplified signal from the transistor also changing. I have connected 12v load LED at the transistor Output section. So it also blinks in a systematic way.

Needed Components:

  1. BC547 n-p-n Transistor.
  2. 2.2k Resistor.
  3. RGB (Multi-color) LEDs (3)
  4. Load LED 12v
  5. 12v Power supply (I used CPU SMPS)
  6. PCB Board (Optional)
  7. Breadboard (Optional)


Circuit Schematics Of LED Blinking Circuit:

Here is the schematics of the LED Blinking Circuit. I have used Basic Components for making the Circuit. You can use a breadboard for testing purposes.

Watch the YouTube video:

How the Circuit works?

  1. This is a Basic transistor Circuit. The LEDs are connected in series with the Base of the transistor.
  2. When the 12v Vcc is on then the RGB LEDs connected in series changes their color in a systematic way.
  3. The changing color triggers the transistors Base. As the Transistor Base Voltage is changing the amplified signal from the transistor also changing.
  4. I have connected 12v load LED at the transistor Output section. So it also blinks in a systematic way.


  1. I have used BC547 for the demonstration purpose. If you want to run bigger loads like RGB LED strips then I will highly suggest you to use High Power Output rated Transistor.
  2. As a power transistor, you can use N-Channel MOSFETs like IRFZ44N N-Channel enhancement type MOSFET.
  3. You can use Heatsink for Thermal Cases.
  4. You can also go one step ahead and try to improve the Blinking Depth by Changing the values of the Resistor Between 50Ohm and its above.
  5. As you are working with a transistor you might know that transistor is a semiconductor device. So it has some resistive characteristics. So the transistor 0.7v for international Characteristics.
  6. If you want to run 12V LED strips then I will suggest you go for 13v Power supply. For this case, the LEDs will Blink with its maximum brightness.

Pros of the Circuit:

  1. The Blinking LED circuit is easy. It requires fewer Components. Great for Hobby Projects.
  2. No I.C. required for Generating PWM.
  3. The circuit will Give You many blinking effects as 3 LEDs are in series, they all LED combines and gives Great blinking effects.

Cons of the Circuit:

  1. The circuit is great for Hobby Projects but there are some problems with the Circuit. If the circuit runs with one RGB LED then the circuit will be effective.
  2. We used some simple components like LEDs for the Blinking. This will not give you as blinking Depth Compared with PWM signal from the NE555 timer.

               Those are the only corns I found in the Circuit. I will suggest you to make make the Circuit yourself and you should try to modify the circuit and send me your Schematics through Social media.
If you have any doubt then feel free to write in the comments section. I read each and every from you guys. This motivates me a lot for writing articles for you Guys.

LED Dimmer Circuit

In this article, we are talking about the LED dimmer circuit. It is a basic circuit made out of 555 timer. Let us try to understand the LED dimmer circuit.

Watch the YouTube video:

Watch the video until the end and you will understand Everything. Here I have tested the circuit and the LED Dimmer Circuit Works perfectly. 

Components Used:

  1. NE555 Timer Click Here
  2. 1K Resistor Click Here
  3. 50k Potentiometer Click Here
  4. 1N4007 Diodes Click Here
  5. IRFZ44N MOSFET Click Here 
  6. 100nF, 10nF Capacitor Click Here 
  7. Breadboard Click Here
  8. DOT PCB Board Click Here
  9. 100W LED Click Here


LED dimmer circuit schematics:

How does the LED dimmer circuit works?

Here we are using 555 timer. You can control the duty cycles of the PWM signal by rotating the potentiometer.   The PWM pulse coming from pin number 3 is driving an N-channel MOSFET. The MOSFET basically dims the LED when it gets slow PWM signal. you can use any engineering MOSFET for any power transistor as per your need. For my case of a LED dimmer circuit, I used IRFZ44N N-channel enhancement type MOSFET. You can use any type of MOSFET as a load you are connecting. I have made the circuit on Dot PCB Board. You can use a breadboard for testing purposes. This is a cheap build which takes all under $1.


  1. I have mentioned the potentiometer about 10k to 50k. If you find 10k is not working great for you then I will suggest you go for the 50k potentiometer. This will solve your low problem.
  2.  If you want to drive 12 volt LED strips then I will suggest you take a power supply around 13 volts. Because for the dimmer we are using a MOSFET, the MOSFETs has its internal resistance. show the most it will take. 7 volt for its work so when you are working with this type of MOSFETs you will add +0.7 volts For great results.

LED Chaser Circuit with 555 timer

Hello, Everyone today in this article we will discuss LED chaser circuit using 555 timer. You can control two LEDs with this circuit. You Can use this circuit for controlling 2 LEDs you can also change the LED flashing speed. You can also control more LEDs by utilization of 2 N-Channel MOSFETs.

Video Tutorial:

Guys I will highly recommend you to watch my YouTube video about LED Chaser Circuit with 555 timer for more detailed information.

Part Details:

  1. 2 White LEDs
  2. NE555 Timer
  3. 2, 330Ohm Resistor
  4. 100K Resistor
  5. 1K Resistor
  6. 1 DC Capacitor(1,2,3,4....100uf)
  7. 9V Battery
  8. 9V Battery Clip
  9. PCB Board.

Circuit Diagram:

How the circuit works?

  1. The circuit is very simple. you can also make this the number 3 pin is the output pin. Number 3 pin gives the PWM signal which is something about logic 0 and logic 1. Logic 0 means 0 volt and logic 1 means 5 volt. Logic 1 and logic 0 alternates in a fraction of time. I mean if you find that the logic is high then after that the logic will be low after that it will be high and it will go on.

  2. Let's talk about logic 1: The logic 1 and logic 0 is sequential. So was let's talk about logic 1. Logic 1 means 5-volt output. Now if you have read the logic 0 paragraph then you can imagine the logic 1. This is logic 1 so it means that the voltage of PIN 3 is 5 volt. So we can say the middle node voltage is 5 volt. Let's talk about LED 2 first. The middle node voltage is 5 volt and the GND voltages are 0 volt. Show current will flow from the middle node to GND. So we can say the led 2 will run.

  3.  Let's talk about LED 1, let's imagine you have connected the circuitry with 5-volt power supply. Show the Vcc voltage is 5 volt and also the middle node voltages 5 volt so there is no potential difference between these two points so we can say the LED 1 will not work.

  4. This cycle continuous one by one. And the two LED glows one by one.

  5. Here the capacitor takes a great role in switching. Let me explain, the capacity at which you have connected is charging and discharging simultaneously. Firstly the capacitor charges and it comes to a threshold point. The capacitor stores the charge up to the threshold value. When the capacitor crosses it's threshold point then the IC triggers and suddenly the capacitor started discharging. The circle will what till the capacitor fully discharged after that the capacitor fully charged and crossed is the threshold point. And the same circle runs more and more. Here the capacity takes a great part. If you use a capacitor with higher capacity, Then the flashing of the LED will be slower. For this reason, I have used female headers for seeing the changes after changing the capacitor.
      Now you come to the conclusion that we use 555 timer for flashing 2 LEDs. You Can also read the new article about LED Chaser Circuit with 4017 I.C.

LED Chaser with only 4017

Hello Guys, Today in this article I will discuss LED Chaser Circuit Using 4017 Lighting IC. Hope you guys enjoy and you will make this project in your home.

  12. Soldering Iron Click Here

4017 IC PIN Out:

Watch The Full Video!!

How It Works?

  1. 4017 IC has 10 Output pins and the IC needs a PWM (Pulse Width Modulation) for running this process. For this case the Pin 14 of the IC Works. For the reason, we use 555 Timer IC for giving the PWM signal. But in this case, we have used a Multi-Colour RGB LED for Triggering the IC. This is the simple concept of the Circuit. 
  2. If you look carefully then you can see the pattern is not always same. Sometimes It goes faster than expected and sometimes it Goes Slower. Here Is the Reason,

    • If you see the Multi-colour RGB LED from Close then you can see that the LED has some Strange Pattern. When the LED Goes Slower than Expected then the PWM Signal Produced from the LED was Low.
    • If you find the LED Changing Pattern is Faster than before, then the PWM signal produced from the LED became very High. As a result, you find that the 10 LED chasing speed Has gone too fast. 

  3.  I have Used a Multi-Color LED you can also use a Dual Colour LED for getting more accurate and a single Pulse as a Signal. You can Use any LED as your wish. For this case, the LED is running in only one state so we can believe that we will only get one PWM signal and the LED Pattern Goes from 1 to 10 in a single pattern.

Circuit Diagram:

             The Wiring will take some time for being complete. After Its doe then you can Gibe the Power anything in 3.7v to 9V for running the LED Chaser Circuit. It is a very Easy Circuit. So, I will highly recommend you to make this simple circuit.

            If you Guys Have Some Doubts about this project then I will request You to write down a comment in the comment section. This highly motivates me for writing such articles for you guys.

How to run android OS in PC?

Why Android OS?

Suppose you have an old PC or laptop. Suppose the laptop is hanging so much and that you cannot work anymore with Windows OS. Now you try to format your PC but it doesn't solve your problem. For solving the problem I will suggest you go for Android OS that will make your PC faster and smoother than Windows. Today in this topic I will be discussing how you can run Android OS side by side Windows 10. So let's jump into our topic.

Different Android Os:

  1. Remix os
  2. Phoenix Os
  3. Android-x86

      There are different os are available for your Android. On behalf of those are you only like the phoenix OS most.

  1. The Phoenix OS is made with 7.1 Nougat. So it means that you can run the most Android application at this time.
  2. Smooth and responsive.
  3. You can use your flash drive for installing this Os.
  4. You can run any high graphics intensive games like PUBG Mobile in this OS in 60fps HDR Ultra settings.


  1. First, download the installer exe file from the link below.
  2. Run the installer file. There will you find three options. In this case and just making my USB flash drive as an Android drive and this drive is 32GB in capacity.
  3. Connect the USB drive into your PC
  4. Select the middle option from the installer this is for making a USB flash drive as bootable so after that, you have to just refresh as select your flash drive. then click on ok and your flash drive making process will be on it will take some time for making the bootable drive.
  5. After that shut down your PC. Then connect the USB drive to your PC or your laptop.  Go to your boot menu. From their search, the USB drive selects that and press enter.
  6. Now, wait for sometime. It may show some errors but don't worry it will automatically boot up with Android. Obviously, you all know the fastboot will take some time. So wait for sometime and it will boot with Android OS automatically.

How to Unlock Download Link?

  1. There are 3 Buttons available Below. 
  2. If you forget any step then you will not be able to download the Desired Content.
  3. Firstly, Click on the buttons Do the tasks that are given one by one first to last.
  4. Click on the first button and Subscribe to Creative Creator. then come back to this page.

  7. If you Skip any step or you have directly Clicked on your desired step then you will not get the Download Link.
  8. Go and Enjoy!!

Now you are all set. You can use your Android as your mobile phone in your PC.

My Recommendation:

  1. If you have an old potato 🥔 PC then go with for this type of OS. It will not slow down your PC and don't Lag anymore.
  2. If you want to play PUBG  MOBILE without any Lag any issue without any graphics card also then this is a perfect choice, in my opinion, it will not give you any leg experience. You can also play in HDR ultra graphics settings.
  3. It is a lightweight OS suggest 600 MB only for Android OS so it is very low comparing with windows.
