Automatic blinds(IR controlled)
This is my control board for automatic blinds. It is very easy controller which you can easy reprogram for yourself by UART. Only what you need is FTDI232 programer. I used DC-DC buck converter for set voltage on each motor. The heart of the controller is ATMEGA 8 but I recommend ATMEGA 328 because she has more memory. I had to remake IR library because this library take up all memory of microprocessor.
