“This Arduino-based tuner uses Simulink to get audio input from an electric guitar and then tune each string based on this input. I have always loved music and have been playing guitar since a very young age. One of the most important things when playing guitar is making sure that the instrument is in tune. Even the best guitar player will not sound any good with an out-of-tune guitar. Tuning guitars by hand using a standard tuner has always been common, but an automatic tuner makes things much easier, and more fun! This Arduino-based project will tune your guitar for you.”
