Data Sheet

INTRODUCTION

A theremin is an instrument that makes sounds based on the

movements of a musician’s hands around the instrument. This

project will use LDR as an input where the amount of light intensity

will determine the melody notes.

This project applies knowledge outcome from:

Lesson 3: Create Melody with Piezo

Lesson 8: Light Dependent Resistor

INGREDIENTS

a. Maker UNO - 1x

b. Breadbord - 1x

Resistor 10kΩ - 1x

d. LDR - 1x

Jumper wires

INSTRUCTION

Using all the parts above and create an instrument that creates melody played

by piezo depends on your hand position. The closer your hand is to the LDR, the

higher the notes that will be produced. When you withdraw your hand, no

sound will be generated. So, enjoy the melody you create!

Note: To calibrate the sensor, move your hand up and down over the LDR for 5

seconds to change the amount of light that reaches it. The closer you replicate

the motions you expect to use while playing the instrument, the better the

calibration will be.
