ESP NOW to Remotely Control Stepper Motors
Channel: Grateful Frog
Date: 2021-06-29

This video demos a future robot controller based on the ESP NOW prototcol offered by ESP32 boards.


The system comprises:
* A Controller running on an ESP32 DevkitC V2 with 4 tactile push buttons acting as Forward &  Reverse controls for each of the 2 motors.
* A Driver running on another ESP32 DevkitC V2 connected to 2 28BYJ-48 steppers via their drivers.
* a single byte is sent from the controller to the driver via the ESP NOW protocol which is really cool, reliable, and quick to implement.
* Both the ESPs and the steppers are powered from 9V, reduced to 5V using L7805CV regulators.
