Two Channel PWM Pulse Frequency Adjustable Duty Cycle Square Wave Rectangular Wave Signal Generator

In this video we will see the review and performance of the dual channel pwm generator.
2 Channel PWM Pulse Frequency Adjustable Duty Cycle Square Wave Rectangular Wave Signal Generator Module to generate square wave for experiment development.

This is used to drive stepping motor driver’s square wave, Generate adjustable pulse for MCU using, Generate adjustable pulse for controlling relative circuit (PWM adjust lightspeed etc).
