Hey Names Jake.
I been playing with microcontrollers lately and need some advice.
I trying to fire as many as possible different relays. I have built several relay boards but even with Arduino Mega, I can only push 50 Out signals to power the MOFSETS that power the relays.
So I either need a controller with TONS (200-500) I/O pins or find a way to cheat the programing, Maybe multiplexing but i don't understand it very well, and don't think it will work for this.
I have come up with ideas of using 2 pins to power one relay so that i can multiply my pins which works, but I'm not a fan of writing thousands of lines of uber confussing code everytime.
(This device is used as a fireworks controller, timed perfectly to music. I did it with 40 relays for the first, but the show is growing FAST)
I have a $1500 Budget, so... any ideas? Theres smoke coming out my ears.
