Play tic-tac-toe against a robotic arm.

A humanoid arm + hand prototype made of balsa wood

A simple rover for line following made exploiting the ARTe Arduino REal-Time eXtension.

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

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

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

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.
