Hi Guys,
I was just thinking the other day how I could do this. Basically what I was thinking about is that there are not an awful lot of holes on the Arduino ProMini so I thought , how can I control , say , 50 LEDs with a byte signature to get around using many pins? I use LEDs as an example of course since as long as the signal goes to the right device thats cool but it's got to be a HIGH signal. So lets say I used 2 pins to control these 50 leds and used some kind of suignature to map the voltage to the correct device. The pins wouldn't be taken up on the arduino so thats exactly what I'm looking for. So lets say I sent 01000000 would reference the 5V signal (assuming 5V is the HIGH signal) to pin 32 and a signal of 00100100 would send the 5V to pin 36 and so on.
As I say , I'm just wondering about it , I've not got anything to show you but I guess what I'm looking for is something like this (attached).
Any ideas If I'm barking at the wrong tree?
