 do you program an ArduinoHow do you program an Arduino? I would like to Program my Arduino I would like to program my Arduino to play an MP3 and send a 9 volt electric signal through a wire at a certain time of the day. How would I code this?

Re: do you program an Arduino It's probably just as much a matter of HW than it is SW.
I recommend a HW MP3 decoder (such as this one) to play the MP3 file. Arduinos use either 5v or 3.3v logic levels, so directly controlling a 9v line is not possible. I recommend using a transistor to switch on/off a 9v signal. _________________ Matt |
