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.
