To solve the problem without sourcing a new switch, [Jean-Noel] built his own Arduino based Dahlander switch. This consists of three relays that select the wiring configuration for each speed mode.

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.

The High Power H-Bridge Motor Shield for Arduino is equipped with built-in current sensing utilizing the ACS712, and is capable of driving any DC motor up to 15Amp.

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 ...

If you want to attach a light, motor or sensor to the Arduino board, you just snap it on -- you can spend more of your time coding rather than dealing with wiring and other hardware hassles.

Electric Paint is an electrically conductive liquid wire, which can be used as a cold-soldering medium or conductive adhesive. Non-toxic, solvent-free, and water-soluble it can be used for prototyping ...
