Digital Guitar Tuner


Posted on Jul 30, 2012

The circuit is a simple, but accurate Digital Guitar Tuner. It samples the input, which can be directly from the mics of an electric guitar, or from a microphone, it you`re using an acoustic guitar. It can ofcourse also be used for tuning other instruments. The samples are then checked against stored values for the strings, and the two LED`s will show the tuning status - `Too Low`, `Too High` or `In Tune` when both LED`s are lit.
