Automated door opener

thingiverse

This is my universal printable automated door opener! I use it for our chicken coop, with a light sensor. But you can also use it for other things! Maybe for greenhouses ,with a temperature sensor. Instructions Generaly its a way to open a door or a window with a Nema 17 stepper motor and a M8 threaded rod! I use a wattduino from watterott.com to run the code! In my solution i have 4 buttons ! (Power on/off,door open, door close, automatic mode) and two LEDs (Power on/off, Debug) The automatic mode close the door when the night come and opens it when the sun rises! The arduino catch the light intensity with a standart light depending resistor and recognize that the door is completly closed with a endstop button. The arduino code is in the .zip! Im working on a full documentation in pdf format!
