Hey, 1. Let's say I have an SD card shield, and I put an SD card with a sound on it into the shield. How do I program the Arduino to play that sound by it's name?
- I want to try simple wireless communication with IR emmiting and recieving diodes. I want to use two arduino board. the code for the emitter will be something like a blink with a 1mS delay. What is the code for the other one? I mean, if that pin is HIGH, than delay 1mS, than LOW and another delay. how do I write that code? on the normal 'if' I have () to put my condition, what if it's a big condition?
Thanks for your patients, time and forgivness for my spelling mystakes ;) and sorry for digging!
