[How To Use] Your Phone Camera for Testing & Checking if a Remote Control is Working?

Remote controls & cell phones are an integral part of our lives. We can live without food for a day but definitely not without a remote control & a cellphone. (OK I know that’s a little too much).

Point is did you know your phone camera & remote control are good friends?

One of my ACs stopped accepting commands from it’s remote & as you can imagine it was a pretty frustrating experience. I tried everything from changing the batteries to 2 tight slaps for the remote (typical Indian Jugaad).

Later when I called my AC repair service, the mechanic gave me this idea. He told me we can check if a remote is working or not just by pressing the remote buttons in front of a cellphone camera.

The thing is remote controls have a light emitting diode that are pretty fast & they emmit signals in a fraction of a second. Making it almost difficult for the human eye to see things in action.

Mobile phones on the other hand process images & are slightly slower, hence they are able to show the light processing with a brief delay.

So next time before start slapping your remote or think the battery is dead, use this trick to make sure if your remote is working fine.
