So the CobraPin has the direct switches and the matrix. Out of curiosity, how hard is it to setup a matrix myself?
If could do an 8x8 matrix as well, I'd only need one blue pill board. Obviously not breaking bank buying another board, just think it'd be cool to get by on one.
My requirements are;
1-2 blue pills for,
At most 50 serial LEDs
28 playfield switches (including the pop bumperish device, which goes to the solenoid board, right?
6 cabinet switches (the flippers, the drain, the shooter lane, the tilt bob, and the start button)
Probably forgetting something there
One solenoid board
And a separate motor driver board (I only really need directional control on one of the motors, but dual drivers for little robots seem pretty affordable.)
I have also been wondering if there is something in the car stereo/accessory area that would fulfill my 12v power filter needs. Going to do some digging.
