The motor controller is commanded over the Arduino’s serial interface, and will support a serial interface to ROS (Robot Operating System) in the future.

Hard-drive based media players aren't anything new, but hifi equipment actually built from old drives are somewhat rarer. At Hifiduino they're using an Arduino microprocessor… ...

This machine uses a three-phase Dahlander motor, which has three operation modes: stop, half speed, and full speed. The motor uses a special mechanical switch to select the operating mode.

Repurpose an old hard disk drive (HDD) to create a powerful motor for your RC airplane. This DIY project shows how to extract and modify components from an old HDD, turning them into a functional ...

Seeing this Toshiba motor drive, my first thought was ‘what a neat chip for pairing with an Arduino’ as it combines operation across 1.8 to 7V with up to 4A drive – so that is Li-ion batteries, 5V USB ...

A teacher I know is stuck, with only npn transistors in the supply cupboard and the need to create a reversible motor drive for an Arduino project. Reversing ‘bridges’ have four switches (relay ...
