Making of phone controlled curtains based on Arduino

I build an automatic curtain opener for my room. I'm using an Arduino Nano clone soldered on a perfboard. The L298N uses the 12V to drive the gearbox motor and also converts it to 5V to power the Arduino. This way I only have to use 1 power supply. Communication happens via Bluetooth and the app ''RoboRemoFree''. I can also use my PC to control the curtains. See my other video for more information.
Thanks for watching :D
