How many times has this happened to you, you pick up the remote point it at the TV to change the channel and nothing happens. Do you do what I do and frantically press all the buttons hoping one will work then give it shake or two and finally give up and replace the battery’s only to find out its still not working. Since TV remotes broadcast their codes in the infrared spectrum you can’t see if it sending anything, until now.
Here’s a tip I found that lets you check to see if the remote is sending its infrared signals to your device.
- Grab your trusty digital camera and turn it on.
- Point your remote at the camera and press any button on the remote.
- If the remote is sending codes to your device you will be able to see the flashes on your cameras display.
