 Bigger Bigger  Smaller Smaller  Reset Reset

I built a driver to send a 2 second 24V pulse to a slave clock once a minute to run the mechanism.  Pretty simple, but it works smiley  some help from mem on the millis timeout.  It's just the standard Arduino standalone without serial communication + a transistor and a DC-DC converter with regulated output.  The link is a blow-up of the board.
