Infra Red Remote Control Tester is a simple circuit that serves to test the remote control with infrared (IR). This circuit will give a response as to receive infrared light emitted from the remote control. Tester Series Infra Red Remote Control consists of an infrared receiver in the form of photo diode, IC 7414 and schmit triger a LED indicator. Tester Series Infra Red Remote Control is working with the source voltage to 5 VDC 3VDC. Picture a full suite of Infra Red Remote Control Tester can be seen as follows.Image Series Infra Red Remote Control Tester. When the infrared receiver on a series of Infra Red Remote Control Tester is received from a remote infrared pancara who tested it on pin 13 IC 7414 will occurs a drastic change in voltage that will give triger to pin 11 IC7414 ynag used to mendrive LED D2 through the IC1d IC7414 . LED D2 will provide appropriate response to the signal received by D1 (infrared receiver) which is a signal from a remote that tested.
