problem with arduino? Answered

I have some questions about Arduino Uno. I connect my board and within 5 minutes (no code is running or anything), the chip becomes hot. Plus, none of the IDE is recognizing my board. I'm always getting the error "avrdude: stk500_getsync(): not in sync: resp=0x00". Can someone help me with these issues?

check the orientation of the IC or the largest chip on it . see photos of arduino and compare them.

try burning a bootloader to it .Anyway does your arduino get recognized by your pc . goto device manager ports com&lpt and find a port Arduino and com port will follow.If you cannot see it as arduino uno it cannot be made to run . if you see one without a name and it is your arduino actually bootloader might not have been burnt.

Any motors /sensors or external circuitry connected?

The fact that the Chip becomes hot is already a big No-No.

This means that the chip is either connected wrongly(will destroy the chip if happens), Its Faulty/fried or the Voltage regulator isn't doing its job.

My advice is to first get that chip out as its most likely fried anyway. Then i would suggest to check the voltage of the 5v pin with the unpopulated board plugged in. if its giving more then 5.4v your regulator is faulty and you may want to replace the entire arduino, if not then get yourself a new chip. Many arduino sellers sell the ATMega328 with the optiboot code pre-programmed on it. this is the chip you want. Don't buy a bare ATMega328 as you would need to program it by a special programmer/other arduino.

Oh if ever using a external higher-voltage power-source allways connect it to the VIN and never directly to the 5V... just a word of caution.

The message strikes when arduino is not able to communicate with the computer.

could you perhaps upload pictures of it if it is fake there is a huge chance of it being faulty. i had that problem

So I need to get a new chip? Would it be because the chip is burnt?

Are you connecting it the right way round + and -

I am connecting the arduino through the cable and it just gets hot. I tried to run the blinking LED code, but it won't run it.

Sounds like it could be damaged.
