Using the arduino IDE I in inadvertently did: Tools->Burn Bootloader ->w/Arduino as ISP...... Since I didn't know what was happening, I closed the IDE, then restarted it, and attempted to compile and upload my program. When I do this, I get:
Binary sketch size: 1968 bytes (of a 32256 byte maximum) avrdude: ser_send(): write error: sorry no info avail
Re-installing the correct USB driver, and power cycling the Uno still results in the above message. My guess is that I corrupted the boot loader. Not sure what to do to fix this....Any guidance is appreciated....
