“Hey, what’s up folks here’s something super cool and useful if you’re making a basic Robot Setup, A MOTOR DRIVER CONTROLLER BOARD that controls the motor driver by an Onboard MCU and has an HC01 BT Module for Bluetooth connectivity.
I added four mounting Holes on the PCB so I could add PCB Standoffs to hold the motor driver on the top side of the board in the air. It’s a clever method to use standoffs as we can add multiple Modules with this method just by stacking them up in a row of standoffs.
I’ve also added an HC-SR04 Ultrasonic Sensor Breakout Pin on one side of the board so it can be used to make an obstruction-avoiding robot.
This Instructables is gonna be about the build process of this motor driver, so let’s get started.
