I've been programming micro controllers like Arduino and Raspberry Pi for about a decade now. While I'm still very much in the hobbiest category I'm still able to do some pretty cool stuff.
I increasingly use a lot of 12V DC LED lighting and I use Arduino's to control them in various ways; motion sensors, remote control. lights sensors and switches. This allows me to push the efficiency of the LEDs even further. And since everything runs on DC I can skip the inverter on my solar PV system which further pushes the efficiency of the whole system.
I also do a lot of temperature reading, inside at various rooms and of course outside. I'm just finishing up a Rocket Mass Heater build where I installed a high temperature thermocouple to measure the heat at the top of the heat riser. So far my hottest temp has been 1,300F! And I'll embed 3 temp sensors in the top of my mass. I'm excited to see how long the mass will hold heat after a fire.
Anyway I'm curious if other homesteaders and permies are using microcontrollers and what your doing with them.

I am not there yet but I am headed there. I have aurdino 256 mega and intend it eventually for a full house controller but the starter project is automating a thermal air solar collector panel. Monitor 4 air temperatures and control 2 to 5 vent doors based on that information.
My current tech project involves the ATTiny85 chip, and a controller that is by default the ESP8266, but can be an Arduino or a RPi. The project is a DIY Powerwall.
I've used arduino's with timers for watering systems in the past, but since we have been back in Illinois I have not been able to do much. If I get the time, I hope to automate the chicken coop a little. A small solar setup to provide power and monitor food, water, temperature, ventilation, and the door. Not that any of those things can't be done manually, like I do now, but it would be nice for the future if we want to take a trip somewhere. Not NEEDING someone to check in once or twice a day for short trips would be nice.
