Hello guys i just accidently poured a coffee to arduino when i working with my project.
Uno was short circuirted and i realized atmega328p-pu is gone. so i bought a new chip and plugged it, now i cant upload sketch on it (i cant choose the port) and the tx rx lights are always on.
I tested it with a 9v battery and everything are same. I thinking the fuse is gone.
When i touch the board, the fuse part is little bit hot.
Please help me, what should i do??
I dont want 25$ goes to the garbage :((
