Arduino Keyboard Project Tutorial

Hey guys!
Today you will learn how to make a mini keyboard with Arduino.
You need:

-4 Resistors: one of 1Mohm, another one of 220ohms and two of 10Kohms.
-Jumper Wires
-A buzzer
-An Arduino
-Arduino Software
-4 Buttons
-A protoboard


This's the circuit:

THE CODE

The code is in the program. Open examples>Starter Kit>Keyboard

If you have an error while compiling the program, then try to fix it by this way:

1. Close the Arduino Program
2. Take out the USB Arduino wire
3. Connect again the wire
4. Open again the program

That is all. I hope you like this little project :D
