hi all
I have the genuio uno bord
I want it to control tally light system with Vmix softer
I have managed to get it partially working with the StandardFirmata example
wit the firmata sketch
the problem is that all of my tally lights are all ways on...
my wiring is ok...
when I check the bord with a fluk betwwen the GND pin and any digital pin it's all ways beeping...
any idia??
tnx!
