    Did the pets eat?

    AM/PM Digital Reminder (Pets, Pills, etc.)

    If two or more people are responsible for something, either both do it, or none. Less often it only gets done once. This is an AVR ATTiny84 project that has features like putting the microcontroller to sleep to save battery. One button is to change from AM or PM, and the other is to turn on one of the LEDs representing the current choice for 5 seconds. The unit then goes to sleep, and the LEDs are off. It is powered by an 18650 and I put it all in a medicine bottle. A description of it's construction, as simple as it is, is at an instructable here: https://www.instructables.com/id/Did-We-Feed-the-Pets/ Current draw: Awake: 5 mA Sleeping: 0.13 uA (!)
