digispark AC control
Version 1 - Last update: Oct 26, 2015

Use a hi/lo signal to control the switching on and off of an AC inductive (or resistive) load.

The opto-isolating Triac is a zero crossing device and so a snubber is only required on the output Triac. The snubber is set to 5ms.

The circuit works for 120 and 240VAC power up to 16A withe selected Triac.
