I have a 328p chip soldered on a custom pcb but it is not working as expected.
Now the voltage between vcc pin and GND pin is showing to be at 1.2 v
i am using lm7805 to convert 12 dc to 5v dc . and i am uploading a blink sketch .
but i am unable to upload.
output of lm7805 is exactly 5v and chip is directly connected to the 5v.
Is something shorting ?
