i was making a circuit with my arduino and suddenly both the green light(power) and the orange led light(pin13) lit up. i tried to reset the board but no change occurred as i pressed the button. then i disconnected my arduino and tried uploading bare minimum to it but it did not upload. i have an arduino uno r3 smd edition. i want to know what is the problem with my board and how i can fix it.please help me. thanks in advance
Is anything connected to the Arduino?
What had you connected to it?
When you plug it in, do you see a port appear iin the tools -> ports menu? This is a good sign.
When you plug it in, do you get a "the last device you connected has malfunctioned" message? This is a bad sign.
nothing is currently attached to the arduino. i had accidentally connected the positive terminal of the arduino power pins to the positive terminal of a power source (two 9v battery power source). i was trying out different circuits in which arduino isolates two circuits when this happened. when i connect my arduino it is visible in the device manager as arduino uno and it is also visible in the ports.No, i did not get any 'the last device you connected has malfunctioned
Some suggestions:(Are you using windows?)
- Try to disable and re enable the device in the devices menu
- Upadte the device driver, Go to device maneger, select the arduino,right click,choose upadte device driver, choose manually/I'll chose what to install,navigate to your arduino install dir, go to drivers folder, choose "dpinst-x86", and follow the process.
