## Troubleshooting:
### Error uploading sketch
```
ser_open(): can't open device "/dev/ttyACM0": Permission denied
```
Add rights to `tty` device:
```
sudo usermod -a -G dialout
sudo chmod a+rw /dev/ttyACM0
```
## Avrdude
Update usbavr:
```
avrdude -c avrisp -P /dev/ttyACM0 -b 19200 -U flash:w:usbasp.atmega8.2011-05-28.hex:i -p m8
```
Flash app:
```
avrdude -c usbasp -U flash:w:firmware.hex:i -p m328p -b 9600
avrdude warning: cannot query manufacturer for device: error sending control message: Protocol error
