Stepper motor is an electronics device and a brushless DC electric motor that divides a full rotation into a number of equal steps. It is widely used in robotics, industry, computer peripherals, motion control, business machines and many other purpose.

There are many techniques for rotating stepper motor. We need to rotate motor any angle that we want. We know that stepper motor is one kind of digital device or digital motor, for rotating this need sequential clock pulse to the specified coil of the motor. For rotating 360 degree angle need specific number of clock pulse which is depends on the number of coil and its mechanism.

The main objectives are - to control the switch using remote as an on/off switch. To determine that the infrared sensor can easily receive the signal from the remote transmitter and to control the Fan speed using regulator. The 38 kHz infrared rays generated by the remote control are received by IR receiver. Pin 2 of IR is connected to ground, pin 3 is connected to the power supply through R1 and the output is taken from pin 1. The output...

AM transmitter is a circuit which can transmit message signal to modulated signal. This circuit is designed with limited power and the required power supply of the transmitter circuit is 9 Volt.

The circuit has three parts that is an audio amplifier, radio frequency oscillator and modulator circuit. The frequency oscillator is built with 741 Op-amp and related components. The carrier signal frequency and its amplitude can be varied using variable resistor accordance with VR1 and VR2 respectively. C1 and C2 are the main components to generate the carrier frequency.

This is the most popular IR Remote control circuit for home appliances like lamp, fan, radio, tv etc to make the appliance turn on/off from a TV, VCD or DVD remote control. It is very simple to build because of few components and simple design.

Really helpful post. I never thought that infrared is used in remote control. Thanks for sharing this knowledge to us. GetmoreInfo related to your post.
