For those practicing music or looking for a source of various “ticking” noises – a metronome is always a useful tool to have. Kerry Wong has described an updated metronome based on the Arduino hardware that is small, easy to construct – and simple for the end user.
The circuit is quite simple and well documented. Although he has used a bare Arduino circuit, one could save a lot of time by using a small Arduino-compatible board such as our LeoStick embedded in the project instead:
Apart from being one of the smallest Arduino-compatible boards on the market with full USB, it also has an onboard piezo which could be useful for sound generation in this project. To get started with your own metronome, visit Kerry’s webpage here.
