BPM Generator module back
The BPM Generator give you +5V pulses output with 20ms length, from 40 to 240 beats per minute. Controlled by a microprocessor. The BPM are displayed with three 7 segment LED. The speed is adjusted with an rotary encoder.
The documentation for download can be found in my website.

Most work is done by the microprocessor. The micro takes care of the output timing and the multiplexing off the display. All four outputs are independently buffered.

Is simple and perfect. Maybe if you use a transistor or an opto input you can use it for possible sync to external source, just an idea
Thank you. I am already planing a next version. With outputs x2, x4 , x8 and sync in and out.
