AT 219 Lab 4 - Arduino Programming Part 2

This objective of this lab was to create a program in which if it’s dark OR a button is pressed, turn on a light AND play a tune. The parts required for this were

1. Arduino Board

2. USB Cable

3. Photoresistor

4. Piezo Buzzer

5. Led

6. Resistors (330 Ohm)

7. Wires

8. Breadboard

9. Tactile Button

This is what the code looks like to achieve this (Figure 1 and 2).

Figure 2: Code (cont.)

The full assembly includes a photoresistor, an LED, a piezo buzzer, and a button (Figure 3). If the button is pressed, or the photoresistor registers a value that constitutes darkness (like covering it with a finger), it will activate the LED and play an ascending C major scale (Figure 4 Video).
