How to Make Almost Anything

My journey through the MIT course

Week 9: Output Devices

This week's task was to add an output device to a microcontoller board we have designed and program it to do something. My focus was on working with a stepper motor, a key component for the peristaltic pump in my final project's watering system. I used a NEMA17 stepper motor along with an A4988 stepper motor driver, which simplifies the process of controlling the motor with a microcontroller.

Setting Up the Stepper Motor and Driver

The A4988 driver requires connecting the STEP and DIR pins to digital output pins on the microcontroller. This setup allows for precise control over the stepper motor's movements and direction. Below are the steps and configurations I used to integrate the stepper motor with the A4988 driver.
