kit is a traditional 555 timer circuit that shows how to extend the timing
period to the maximum.
The relay is activated when the START button is pressed and turns off either after time-out or by pressing RESET. The delay time period is adjusted via the onboard trimpot.
Two capacitor values are provided to give different timing periods. The first gives a timing period of <1 second to approx. 10 minutes and the other covers from 1 second to approx. 20 minutes. LED status indicator.
