ir infrared detector circuit diagram

Men in particular enjoy the convenience of television remote controls often to the annoyance of their female partners. Men apparently want to know what they re missing when the TV is tuned to a particular program, so they like to keep zapping to other channels. With the remote control in their hands, they feel like they are the lord and master of the TV set. They are thus completely at a loss if the remote control doesn t work properly. There are many reasons why a remote control unit can malfunction, such as defective IR receiver in the TV set, a defect in the remote control, or empty batteries. Here a tester that can determine whether the remote control unit still emits an IR signal can come in handy. If you want to keep the IR reins ?rmly in hand, you can build your own IR detector..
