A friend approached me regarding a problem with his public toilet. Currently there are 12 of them scattered in Amsterdam's city core and they are unlit and not provided with a sign to indicate if they're open for use. The accompanying picture is the prototype of my solution. I have a new design, but when it comes to the role of the micro controller, not much has changed.
It needs to go on and off at certain times and it must be possible to override the the clock via bluetooth(BLE) (meaning toggling on/off regardless of the time). It would be great if it was possible to upload new code via BLE. Also, the battery charge needs to be gauged.
Because I lack coding experience I thought it would help to publish my project here. Throw out a line so to speak and see if there are any Samaritans who would like to help me expand my skill set.
