Example code for creating musical New Year effects with Arduino and a piezo buzzer. #define NOTE_C4 262 #define NOTE_D4 294 #define NOTE_E4 330 #define NOTE_G4 392 #define NOTE_A4 440 #define NOTE_B4 ...

In this experiment we are going to work with a sensor which is a resistor that depends on light. In a dark environment, the resistor will have a very high resistance. As photons (light) land on the ...

This will guide you on how to play musical notes of any song on a piezoelectric buzzer, using Arduino Uno R3, a resistor and some connecting wires.
