Any thoughts, circuits, caveats?
I would also only use it on outs and make it disconnect on pins being used as input.Any thoughts, circuits, caveats?
Well as I told lefty, another discussion in a different section about possible shield ideas lead me to consider adding LED status circuits to each of the digital lines on my Cidekick project http://arduino.cc/forum/index.php/topic,67044.msg493322.html#msg493322 but I was trying to figure out how an isolation circuit would work for each pin or if it was even needed.The idea was an LED shield that would show the status of each pin high or low and I was thinking RGB for the pwm pins rather than just fade.The whole idea would only work if it it could be electronically transparent, meaning not affecting other circuits or uses to display the status and if it was low component count.
Couldn't think of a clever way to spot floating pins though, that would be useful...
