Tiny project to push climate control button every few minutes. Every day work space was designated as a meeting room. The power to be decided that such a room should only be ventilated when somebody pressed the climate control button, indicating that it was in use.
Quick and dirty
The problem is that many years later, it is just a regular office work space. Instead of having to press the button half hour, I hacked together this small apparatus to do the clicking for us.
It's a servo controlled by an Arduino and powered by a cheap USB battery bank that presses the button every few minutes. Saving the hassle and time of doing this highly repetitive and demeaning action ourselves.
