I need help. I am trying to use the beacon pairs with arduino with my students in an engineering class. I bought the sensors but neglected that they needed 6V-16V and the board only provides 5V. So then I plugged them into the VIN pin on the Uno board and powered the board with a 9V battery. The sensors then worked and could sense a TV remote, but not the other beacon. I need to be honest and admit the the direction lights when I use a TV remote are not reliable - they mostly light up 180 degrees from where the remote is (perhaps the signal is bouncing off something?
I then powered the other beacon with a second Uno board (as will happen when students use them to sense a cat and mouse robot) but the beacons do not detect each other and I cannot see a regular IR transmission signal as is shown in the demonstration video that is posted on the product page. What am I doing wrong?
Is the enable pin required for the beacon to transmit a signal?
We tried this without the lights on to test to see if fluorescent lights were interfering, no difference, still same problem.
Is it possible the 9V battery doesn’t provide enough amperage?
I know these should work with the code and wiring setup I have but cannot seem to get them to detect each other.
Any advice? I need to get two detectors to detect each other so students can play cat and mouse and not sure what the next steps are.
