So a simple ATTiny85 can control the power to any attached electronic µC device (3v-20v, 800mA-20A) which can include a DC-to-DC Buck-Boost circuit if you need higher voltages.
This builds on our previous circuit and adds a shedload of intelligence to the digital logic we already have. Best of all, you can tweak the code to suit whatever application you have in mind!
