Only pin13 works as output and it bleeds to other pins

Post by HeatXfer »

Just received my UNO starter kit.
Following the 'MyBlink' tutorial and using the tiny breadboard with resistors & a 5mm red led - works great until I reassign the output from pin 13 to pin 7 in the sketch as suggested: the on-board led goes out and pin 13 output drops to approx half (very dim blinking led). When I move the output jumper to pin 7 the external led does nothing and the on-board led stays lit continuously. When I remove the output jumper the on-board led remains lit with no blinking. This result is the same when I assign the output to any other pin.

Is this a known issue? I wasn't able to find anything like it described in this or the Arduino CC forums. Thank you.

Please post your modified code and a photo showing your wiring.

Your digitalWrites are still referencing "LED_BUILTIN". You need to change that to "led"

Thank you. I had previously changed that line to LED and it didn't work. I didn't realize it was case sensitive.

Thanks again!
