AVT740 A

A great arrangement for entertainment and experiments with the "mysterious" VCO generator. Frequency tuning is performed smoothly using two touch sensors. Proper selection of parameters makes the module perfectly suited to emulating police sirens. High speed tuning and the ability to switch frequency ranges (jumpers) allows you to generate hundreds of different amazing sound sequences.

The device is especially recommended for fans of sound experiments and constructors learning about the operation of the VCO generator
