So you're saying it's as simple as adding:
void setup() {
// set up serial port
Serial.begin(9600);
randomSeed(analogRead(0));
putstring_nl("WaveHC with 6 buttons");
and an antenna? I have two inches of copper wire now poking out of pin 0. Now it is playing a different song each time I start it up, which is hopeful, but not random yet. Am I doing something wrong? Please forgive me I'm totally new to this.
Cheers!
