The video demonstrates how easy it is to send SIRC codes from the transmitter to the receiver. Simply power up both circuits and press either SW1 or SW2 on the transmitter. At that point, the blue LED on the transmitter should flicker to indicate that data is being sent via the IR LED. Simultaneously, the blue LED on the receiver should flicker to indicate that data is being received by U2. In addition, the stepper motor connected to the receiver should begin to turn; SW2 causes clockwise rotation while SW1 causes counter-clockwise rotation. The LEDs should continue to flicker and the motor to turn for as long as either switch is pressed.
