Hello People!

This instructable is about how to build the simplest(probably) PWM circuit to control DC Motor speed, LED Strip Brightness, etc.

Specs:

Input Voltage : 5-30v

Current Handling : Depends on the MOSFET(Around 10A for IRFZ44)

Please comment if you tried building it!

<p>Clever circuit. I also like the use of the bottle cap as a control knob.</p>
<p>What advantages does this circuit posses over the more popular 555 PWM designs?</p>
<p>Here are two</p><p>One advantage might be higher operating voltage and other might be that two individual controllers can be designed using a single IC</p>
<p>Both are excellent reasons, thanks for the reply!</p>
<p>Nice basic control circuit design.</p>
