Hi, I am a beginner in arduino.
I recently am working on a project on esp 32 cam model. By mistake I gave a 7 volt input to the esp. Now the onboard led is continuously running whenever i power on the board. No matter what code I flash into the board the led never turns off. Rest of the board is functioning normally. Now my questions are
If due to the excess voltage the board has fried then why is the board still working?
Is there any way to rectify this or i have to buy a new one?
I am in quite a fix, any suggestion would be very helpful.
Thank you.
Best guess is you didn't have anything other connected to the board (is this true). But the LED was connected as its on the board.
So it would seem the chip was stressed but survived except for the one output, which due to its load was over heated and failed ON.
I would purchase a new board because you don't know if other parts of the processor are overstressed and are ready to fail.
However I would continue to use the "damaged" board until you have your hardware stable.
First of all thanks for the reply.
Actually the esp board was in fact connected to 2 motors via l298N. I gave 7.4 volts to the l298n and seperately 7 volts to esp board. It was running fine for like 20-30 seconds after which it stopped. And when i reconnected it with a 5v source it is again working fine except for the burning led.
