To start, the idea is to record a sequence of button presses (and releases) and have the arduino play back the pattern on the speaker.

Exercise

Create a program to time how long the user presses a push button.

Step 1

Starting code / circuit:

http://arduino.cc/en/Tutorial/Button

Make sure your pushbutton circuit is working.

Step 2

The following pieces will be useful.

Print out a message (to the compute, use the Arduino Serial Monitor):

Serial.println("hello");

Get the current time(in milliseconds):

s = millis();

Exercise

Write code to translate the presses from the user to a fixed pattern
