Practical IR remote control tester – practical method with camera, digital or cellular. It is a way it practices of testing an infra-red remote control of any apparel it is dvd, TV, micro systems, using a digital camera or an apparel of cellular.
If a remote control is failing, the problem in it can be him remote control, it can usually mean that the piles are out of print. If you change the piles for new and even so not to solve. Here is a subject, the issue is in the remote control or in the device that want to control. Since we observed basic subjects as piles with inverted polarity or you plunder with defect. It remains now to check the remote control, it transmits some sign. We typically used testators of GOING, easily gotten with a photo transistor. But that equipment type usually meets at our laboratory. Here is the solution, now we can use a camera digital or cellular. Evaluatable in almost at every moment, with certainty you that is reading that clue, has some of those apparels close of you! In that way allowing to verify a remote control where you are to meet quickly.
It works in the following way, when we pressed a key of the remote control
gone back to the sensor of the camera, we should see in the display a light brilliant, originating from LED to Go of the remote control. If the LED doesn’t ignite, we can be sure that the remote control is with a defect. That happens in reason the sensor of those equipments they are sensitive to the visible light and also to rays infrared, presents in the remote controls, that is what allows removing pictures in the night.
Below we have images of the procedure, interesting the image totally gotten in atmosphere darkness, it seems until other thing.
