On this sample I would like to explain why PID-control should be used for speed controls and how the direction can be inverted.

This project shows you how to successfully control a robot arm using the L9110 motor board, without using up all your Arduino outputs.

Robot wirth stepper motor via microstepping, digital motion processing, auto tuning, cascaded PID controller and now with Joy Stick Control.

A simple Arduino/ESP32 crawler with PS4 BT remote control, but with 2x MCU and an advanced CAN-based communication ("drive-by-wire").

Play tic-tac-toe against a robotic arm.

Make an R2-D2 replica and control it by an app you programmed. Add a Nokia interface which gives you the Star Wars characters info.

Play Connect Four (the common board game) against a robotic arm.
