  • An Arduino Stepper

    A local church is probably typical in that although it has a large pipe organ with a multi-level combination action, it lacks any form of piston sequencer. Trained in the British organ playing tradition, the organist asked whether I could add a European style piston sequencer (stepper) that steps through the generals. This is a fairly straightforward application for an Arduino, so I assured him it could be done.
    Implementation includes installing a two-digit seven-segment display, which indicates which general piston was last "pushed," and forward and reverse pistons/toe studs. Wires coming from the general pistons connect to the Arduino which then controls the combination action by means of a pair of relay boards. Total cost: around $50.
    The introduction to the code (not my prettiest) gives more details and may be found on my website:

    If anyone is contemplating tackling a similar project, there is additional advice I'd be happy to share.

    This is probably my last Arduino application unless there is interest in an organ bench with automatic height adjustment and facial recognition.

    I'd like to see that!
