For this week’s assignment, I use the sound sensor to control the LEDs depends on the different levels of the sound inputted.

List of Materials

1 x Elegoo Uno R3

1 x Full sized breadboard

1 x sound sensor

3 x LEDs

How it works:

three LEDs will blink when the sound’s value changed, but I noticed that the sound sensor is not that sensitive to detect the accurate sound.
