At that time a I also started my journey with micro-controllers so I wanted to connect this two passions to build something fun. I was complaining on having to stand up from bet to turn off my desk light at night (like an animal...) so I ended up with an idea to build a simple relay controlled light from the app. For this project I forked a HM-10 terminal app from github, I striped the whole app down to have only one big button at the screen... For the hardware part I used the Arduino Uno, HM-10 bluetooth module and some relay. I recreated the schematic at Circuito because I never soldered a proper prototype. I also couldn't build my swift project, because it missed some of the files. Archiving some of my old stuff is not an easy task...
