Learn how to build a simple dual PWM circuit using op-amps on a breadboard. In this step-by-step tutorial, I’ll show you how to create two PWM signals where the second one is inverted and never overlaps with the first.
We’ll go through:
0:00 Intro
0:07 Building the oscillator with resistors, capacitors, and an op-amp
7:42 Using a potentiometer to adjust the duty cycle
12:12 Generating clean, non-overlapping PWM outputs
15:27 Testing the signals on an oscilloscope
This is a great DIY electronics project if you’re working with MOSFET drivers, motor control, or just want to understand PWM generation at the circuit level.
