Digital Input to Microcontroller
Most microcontrollers run on either 3.3V or 5V logic, whereas Eurorack gates and triggers are usually between 5-8V....

Here’s a list of open-source building blocks for Synth DIY projects. These are tried and tested circuits, so hopefully they will prevent you from having to re-invent the wheel when it comes to commonly used elements.

Many digital modules will need at least one CV input, however you have likely noticed that while Eurorack can have ±12V travelling through its patch cables, most microcontrollers will be very unhappy to receive anything outside of the range 0-3....
An optocoupler allows signal transmition between two isolated circuits with two parts: an LED that emits infrared light and a photosensitive device (LDR) which detects light from the LED....
