Control Your Synth With Light (Photoresistor Tutorial)
In this video, I show how to use a photoresistor (LDR) to control the pitch of an oscillator and add organic randomness to your DIY synth.
This is a simple and powerful trick you can use in:
CD40106 oscillator builds
VCO control circuits
Sequencer tempo modulation
What you'll learn:
How a photoresistor works (light = resistance change)
How to measure it
How to use it in a synth circuit
How to create expressive, light-controlled sound
This is part of my DIY synth experiments — simple circuits, creative results.
Try it yourself and experiment!
