That’s odd. It’s the first time hearing a problem with the remote control on the GoPiGo3. Have you tried a new set of batteries?
You are saying it worked for a day and then it stopped. Since you’ve flashed the image a couple of times, then it doesn’t make any sense for the remote to not work, unless there’s something bad going on with it.
Let me know if it works when you get your replacement remote.
Thank you for the replacement remote. Unfortunately, the issue is duplicated with the new remote. Would you be able to send me a program that incorporates the remote so I can test it on our end? I am ready to blame the programmer (me) and figure this is a good next step.
Here’s what I posted earlier in the thread. These are the symptoms. We wonder if the button overlay has been reversed in this batch - my student noticed that this version of your remote (https://www.dexterindustries.com/product/infrared-remote/) has the directional buttons at the top and the numeric keypad at the bottom. Our remotes have the directional buttons at the bottom and the keypad at the top.
Note that I have tested this on two separate robots with two separate remotes and IR receivers.
