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! #diysynth #diyelectronics #electronicproject Small Amp : https://www.youtube.com/watch?v=tzIqYkO_YXo CD40106 : https://www.youtube.com/watch?v=x2Jt1os23UM
