I designed a programmable timer to address the shortcomings of the existing timers on the market. My H8/38024F-based design allows an entire sequence of time intervals to be preprogrammed and executed one by one. It beeps briefly at the end of an interval.

As you’ll see, the timer is the perfect tool for monitoring time-sensitive activities like exercise routines. My yoga class uses it.
