Everything was fine until I chose auto format. Now i get a not in sync error. I tried reinstalling and continue getting the error. Please help!
It works on a different pc, so it is not the board.
Using arduino nano ATmega328P... I am a newb and not sure what other info is useful
Autoformat doesn't change anything, so that's unrelated.
Don't recognize the error, so how about actually exporting it from the IDE, and putting it in a quote in your next post?
edit - if it's a clone Nano, did you install the CH340 Serial driver for the new PC?
You might want to look at this How to get the best out of this forum before you proceed any further.
We only know what you tell us, and without knowing what you have, we don't stand a chance.
You have not provided anywhere close to the information we need to solve a problem. Like software listing and wiring diagrams.
The not in sync error occurs when the Arduino can't communicate with the hardware. Like when you have chosen the wrong board to use.
Verify your IDE knows your board and port.
IDE >> TOOLS >> BOARD >> AVR BOARDS >> your board
IDE >> TOOLS >> PORT >> your port
(Nano with CH340)
IDE >> TOOLS >> PROCESSOR >> old bootloader
