The Java program can also read an Arduino program file and convert all the print calls in it to use the library, if you like. As you might expect, this requires some cooperation from your program.

He wanted to see if he could write some code to read that file on his own hardware. All it took was an audio jack and two jumper wires to get the Arduino ready to receive the audio file.

If you want to develop a program on Arduino with Raspberry Pi, then this tutorial has all the steps you need to take for it, in detail.
