Sound Reactive LED Schematic
Lots of people have been asking me for a schematic for my sound reactive circuit shown here:
So without further delay, here’s the schematic:
Note: You’ll have to add resistors based on your supply voltages and your LED voltages. The two LEDs I used ended up not needing a resistor, but if you use a higher input voltage, or have less-powerful LEDs you’ll need to add a resistor between the + voltage and the LEDs.
