STEPPER MOTOR CONTROL USING IR

STEPPER MOTOR CONTROL USING IR

STEPPER MOTOR CONTROL USING IR

The project deals with the design and development of hardware and software for Wireless Stepper motor control system. 

Rotating the motor anticlockwise or clockwise, or completely stop the motor can be done easily with an IR remote without actually going near the motor switches and operating them manually. The manual operation of the motor is completely avoided in this project.

IR remote acts as the transmitter in this project. When a button is pressed in the remote, the signal will be passed and received by the IR receiver TSOP Receiver. This signal is sent to the microcontroller which decodes the signal and performs the corresponding action in accordance with the button pressed in the remote. For example, if number 1 is pressed in the remote, the motor has to rotate anticlockwise direction. The other tasks will be performed in the similar fashion using IR.

Since the microcontroller cannot drive the stepper motor, current driver called ULN driver is used in this project. LCD display is provided at the receiver side to display the status of the stepper motor.

This project uses regulated 5V, 500mA power supply. 7805 three terminal voltage regulator is used for voltage regulation. Bridge type full wave rectifier is used to rectify the ac out put of secondary of 230/12V step down transformer.
