Arduino code

1. Make a sketch that plays the first line of "Happy Birthday" a) C4 (1 beat), C4 (1 beat), D4 (2 beats), C4 (2 beats), F4 (2 beats), E4 (4 beats) 2. Add 2 buttons to the circuit. For a reminder of how to hookup and pro- gram buttons, see section 3.1. When you press each button have it play a different tune. 3. Change ourTone() to not use the tone () and noTone () functions. (HINT: use the technique shown in section 4.2.) 1. Make a sketch that plays the first line of "Happy Birthday" a) C4 (1 beat), C4 (1 beat), D4 (2 beats), C4 (2 beats), F4 (2 beats), E4 (4 beats) 2.
