Versatile Event Counter
Approx construction cost US$40
I would like to be able to establish the beat rate of various musical tracks on CDs. I have made many enquiries but without success, apart from one company who suggested it could cost about 5,000 UK Pounds to develop a suitable circuit. Can you help?
In fact there are many other situations that could benefit from beat counting - keyboard typing rates, for example; rowing rates for another; counting objects passed a point, and so forth. So this constructional article presents a PIC-microcontrolled design that will monitor the timing of all sorts of events. The results are displayed on an alphanumeric liquid crystal display (LCD).
More details on this construction project can be found in the April 1999 issue of EPE Online, the world's first web-delivered electronics and computing hobbyist magazine.
