This circuit is 73 MHz Hallogene Radio-Controlled Lights. The purpose is to control the power state of a hallogene light by remote control. When we press the push of a remote control Botton, state lamp power will change, so, if the lamp is lit, it will be turned off and when lit, it will be turned off. If we press the button for another time, the same action will occur. When the button is pressed, the LED indicator lights on the remote control. This system consists of two separate circuits. One is the remote control, or emmetor. The other is the receptor, or hallogene lamp controller. We input connector from the controller circuit to the light source to 120VAC supply sectors that. The lamp must be pluged the output of the circuit to be supplied and controlled. The following is a schematic drawing:

The circuit also controls the antenna to receive signals from the remote control. Remote control is also an antenna to send signals to the controller circuits and must be powered by a 9V battery. Two important things to my circuit is not mentioned in the scheme. There are about two logic components. The first is a Schmitt trigger NOT gate (74LS14). Its Vcc pin should be connected to the output of 5 V regulator (7805). And GND pins must be connected to the ground from the circuit. Second is the JK Flip-Flop (74LS76). Its Vcc pin should be connected to the output of 5 V regulator (7805). And GND pins must be connected to the ground from the circuit.
