Hello,
I am using an Arduino Uno and have recently run into an issue. When I ran it yesterday everything worked fine, but today my computer failed to detect the board when it was plugged in. I've tried with a different cable and with a different Arduino board, have checked for driver updates and OS updates, have tried manually resetting the boards, but nothing is working.
When I plug in just the board, my computer can detect it and it shows up in my device manager. However, when the board is also connected to the circuit, the on light slowly fades off and my computer loses connection with it. Is this a memory issue? If so, is there a way to fix it?
Hi,
show photos and schematic (even freehand) of your project.
I don't understand your statement below.
What does "when the board is also connected to the circuit," mean?
Two boards same symptoms, so what does that suggest to you? To me it suggest whatever "the circuit" is would be overloading your board(s). Post a drawing and please explain what "the circuit" actually is. The fading LED is a good indicator things are being overloaded.
