We are trying to use CVBoard to control a modular synth using Arduino.
CVBoard is a board that allows you to connect Arduino directly to a modular system, without going through other interfaces.
In this first test Francesco Corvi, to whom we owe a big thanks because he is one of our first testers, has used an ultrasonic distance sensor to transform this quantity into a signal capable of modifying the sound produced by the modular synth.
Francesco shows the just soldered CVBoard! As you can see, the Control Voltage signal outputs use mini-jack connectors that allow direct connection with the modular.
