Click Output from Arduino

[Baran Ismen]

I've found this beautiful project that includes everything for a small gig player like me in terms of BPM counting. It also has a click output via Piezo.

I wonder now if it is possible to use a 3.5mm output instead of piezo so that I can use some in-ear's to hear the BPM on the live stage. If not, would a basic booster circuit help to increase the sound to a headphone level?

It should be as simple as replacing the piezo with an output cap and a jack socket.

From the code, it looks like it's using a timer to create a tone, so the output is going to be a 5V square wave.

Hey Tom,

Yes, its a simple timer with display and everything, apart from tap tempo.

I didnt know that arduino produces a soundwave that is hearable, though it uses a pwm output. Ill give it a try indeed! Thanks!

Switching from a piezo to a 3.5mm output for in-ear monitoring is feasible. There are various amplifier circuits available that could help with this
