Chris from PyroElectro has posted his plans for a 10-A H-Bridge motor controller that avoids using the the typical controller ICs. He writes:
Motor control is the core heart of robotics. Without locomotion or any movement a robot is dull and lifeless. The H-bridge is a tried and true concept for DC motor control. It allows you to move motors forward, backward and with varying speeds through PWM (pulse with modulation).
This tutorial will take a few steps back from the all-in-one L298 or LMD18245 motor control ICs and look more into how we can build our own H-bridge without the need of an IC.
Thanks Chris! Via the contact form.
