What components do I need to build Light Theremin?

You'll need 6 components: Arduino UNO, Breadboard, Photoresistor (LDR), 10 kΩ resistor, Piezo buzzer, Jumper wires ×6. Each comes in the matching Drishti Innovations robotics kit.

How long does the Light Theremin project take?

Around 35 minutes from wiring to working build. Difficulty: Easy.

What will I learn from building Light Theremin?

Read a photoresistor as a musical input. · Use the tone() function to produce sound on a piezo. · Calibrate a sensor's min and max at startup.
