I'm still really new at working with triacs and understanding them, but I want to make a circuit that allows a microcontroller to turn on/off an AC signal (very low power, not mains, don't worry) to blink and sequence EL wire.
and tried to build a simple version of it. BAT +/- is a 3-4V (depending on charge level) DC battery, AC1 & AC2 are the output of an inverter fed by the same battery. the loads are connected across OUT1A/OUT1B, OUT2A/OUT2B, etc.
my issue is that when I connect the gate pin of one of these triacs to VCC, the el wire turns on (great!), but it also turns on when I connect it to ground (bad!). if I leave it floating, the el wire is off.
did I do something stupid here? I'm still learning the nuances of these things and I'm not sure where I messed up.
thanks so much!
