Your powerful friend, the transistor can control high-voltage motors and lights from a microcontroller pin.

Robot arms are awesome! In this tutorial we explore how to control one of them using a Nunchuk and an Arduino Mega.

Use Serial Monitor to test TB6600 Stepper Motor Driver and stepper motor

My first project in Arduino platform. I combined two features in this project, Bluetooth control mode and obstacle avoiding mode.

Really simple robot platform that can find it's own way around obstacles

Drive a bipolar stepper motor with the EVALSP820 -XS and Arduino Mega 2560.

Fun Arduino project using Arduino Mega and servo motors, imitating motion of ants.
