1. Let's say I have an SD card shield
How do I program the Arduino to play that sound by it's name?
What is the code for the other one? I mean,if that pin is HIGH, than delay 1mS, than LOW and another delay.
what if it's a big condition?
What about the code?
int state = digitalRead(IRPin);
I need to right the statment that if it gets HIGH
if it gets HIGH, delay (1), LOW, delay (1), HIGH, delay (1), LOW, delay (1)
