I need to connect a pair of UNOs together over serial the first (master) will be connected to PC using normal USB that's working fine :)
I want to be able to pass commands to a second UNO (slave) my plan (four-letter word I know!) is to use SoftwareSerial on the master and connect pins 11 and 12 of the master to pins 0 and 1 of the slave
I tried, but with little success is my plan flawed?
any help much appreciated:) thanks
