Long Duration Timer using ATtiny2313

Published in issue 391, July/August 2009

Long Duration Timer using ATtiny2313
This timer circuit is designed to switch on a 12 V load in a solar-powered installation for a preset period at the press of a button. When the period has expired a latching relay disconnects both the load and the controller circuit from the 12 V supply. The length of the period can be configured by making suitable changes to the microcontroller’s source code.
