some of my micro usb chords that came with my circuit playgrounds have “disappeared”. (great). so I had some of my own. The program does acknowledge it (lights up rainbow) in the beginning. But, when we run a program, we get the error page. Something about serial ports. Anyone else have this problem?
I’ve heard of similar issues with some folks. We discovered that they were using usb ‘power cables’ instead of usb ‘data cables.’ I’m guessing the lights are coming on because power is getting to the circuit playground, but data is not being transferred. Their solution was ordering some data cables in bulk online.
hope that helps!
