DC Motor Speed and LED Brightness Controller Circuit using PWM | 555 Timer Project #11

A tutorial on how to make a PWM (Pulse Width Modulated) controller circuit for controlling Speed of DC Motor and brightness LED's and LED strips. This circuit controls the speed or brightness by pulsing the output ON and OFF several times per second.
Explanation of how this circuit works is also included in the video.

Components Required:
* 555 Timer IC
* Resistors: 1K, 100R
* 47K Potentiometer
* 100n Capacitor
* 10uF Capacitor (For smoothening power input)
* PN Diodes * 2
* N Channel Mosfet (I used IRFZ44N)
* Breadboard
* Few Breadboard Connectors
* (5-12)V Power Supply
Note: Mosfet is required only if you are using this circuit to control geared DC motors or LED Strips. It is not required for controlling single LED's.
