Help. Arduino wouldn't connect

[bhargavshankar]

My Arduino Uno is not lighting up when I connect my laptop to it. I've tried using 2 data cables and 2 laptops , and still no luck. My Arduino's ON led doesn't even light up. It turns on for a fraction of a second when the cable is entered halfway through. Please help I have a competition in 3 days !

Edit :- It was my fault not the arduino's. I stupidly connected two 5V instead of one 5v and one GND. That's why the arduino just shut down and heated up incredibly high. I was visibly able to see sparks from the board. Sorry its my bad. Thanks for helping

Sounds like it's stuffed.

Is the Arduino Uno recognised by the IDE?

[bhargavshankar]

No. It doesnt show up in COM3. The board is excessively heating up near the port .

[bhargavshankar]

What does that mean?

[paulpaulson]

Post a picture of the hardware setup.

I have tried to turn it on with vin and 5v ports. It has to be a board issue I think

[paulpaulson]

Disconnect all cables from the Arduinio and check again.

[bhargavshankar]

Yep seems to do the trick. Thank you so much
And also I will let you know if my model works .

[paulpaulson]

Take care and keep in mind the Arduino isn´t a power supply unit.

[bhargavshankar]

What does that mean ? ( sorry i recently started arduino )

[paulpaulson]

The Arduino isn´t made to power supply external hardware like servos, relais etc.
