AUTOMATED WIRELESS WINDOW BLINDS
HIGH TORQUE 12V DC MOTOR & 2-CHANNEL WIRELESS RF CONTROLLER RELAY SWITCH

Project Overview
This project aims to turn any regular window blind into a fully motorized automatic wirelessly controllable blinds. Using a 12V 4 Channel RF relay switch and a high torque 12V DC motor, I designed this system that controls the blind strips to allow a certain amount of light in the room according to the user's preferences. It can be stopped at any point and reversed. It uses an RF antenna to receive a signal from a wireless remote. To learn more about how this system works, keep reading.

Switch Wiring

The wiring for the switch is fairly easy to do. The relay module has 2 terminal blocks and each terminal is numbered from 1 to 12 and the 12V = to 12V input and GND = ground. this specific relay switch is intended for 2 DC motor control but I only used the first terminal block for only 1 DC motor. The other can be utilized after wiring both as shown in the wiring diagram to the left, other functions such as rolling the blinds all the way up or down rather than just flipping the strips. I may do this in the future since I only have 1 DC motor at the moment. I used mini jumper wires for the terminal to terminal connections and long Dupont wires for motor and input power supply.

The motor had red and black stranded wires. For easy connections, I attached Dupont wires to the stranded wires using some heat shrinks. This way when I connect them to the terminal block, they look nice and give a solid firm connection.

This Video shows the project in action. I have the motor connected to terminal 2 and terminal 5 on the first terminal block that is controlling relay 1 and 2. The supply voltage is set to 12V. Once I push the switch that controls the relay 1, the motor turns clockwise and switch 2 will do the opposite. The project is still not finished as I am waiting for the motor mount and a connector that connects the shaft of the motor to the blind rod.
