This article briefly describes the Infrared Remote Control (4093). This principle is easy to understand, but also very practical. Depth understanding of circuit elements, you can better grasp this principle. In this circuit, you can learn about and buy these components: 4093.

This circuit will allow you to turn on any piece of equipment that operates on 115 volts ac. The receiver circuit is based on the Radio Shack infrared receiver module (MOD), part number 276-137. It is also available from some of the other sources listed on my Links page. TheMODaccepts a 40khz IR signal that is modulated at 4 khz. When a signal is received theMODwill go low. The sensitivity of theMODis set by different values for R1 and C1. The values for R1 may need to be as high as 10,000 ohms and for C1 40uf. This will prevent the unit from turning on under normal lighting conditions. You will need to experiment with the values that work best for you. The output of the 4013 chip a flip flop toggles on and off with the reception of a IR pulse. The output of the 4013 turns on theMOCoptical coupler which in turn switches on the triac and supplies power to the AC load.
