I connected a DC Motor directly to GND and 5V of my NANO and i think i might have blown it.
Is there any way to fix this, because i think i lost two Boards that way. If i connect it only the PWR LED is on and it doesnt get recognised by the PC. i already tried switching cables and computers. I ahd connected it to those two Pins.
I think it's quite possible that you've blown the Nano. The Nano should not be used as a power source.
Toss the boards, chalk it up to experience and buy some new boards. And don't hook the motor directly up to them again.
Thanks for the fast Answer i bought a Pack of 3 for cheap so i guess it is how it is
Did the motor run and for how long?
it didnt run it imeadiatly shut down like after half an second
ok. Don’t change any wiring while your next Arduino is powered up.
What type of motor?
The nano should survive the small ones.
Some here are a bit hysterical about these things. But the Arduino kit has examples with motors fed from the 5V of UNO.
And I never broke an arduino with such motors...
Was your motor allowed to run freely? Current can go up really high when the motor is stalled.
i just straight up connect it so yeah i guess it was allowed to run freely
in the kit they let it run on a 9v block tho.
but i also never had problems
- Connect the Arduino to the PC, remove all wiring to the Arduino GPIOs.
Upload the blink sketch, does the Arduino L LED toggle .
the PC doesnt recognise it, i also tried different cables and pcs only pwr LED is on
damn i just throw it in the bin and take another one without doing the same mistake again, huge thanks guys
- What voltage do you measure between the 5v and GND pins ?
i didnt yet but probalby nothing if a LED doesnt even light on
- Measure it and get back to us.
