Resources & Going Further
For more resources, check out the links below:
- GitHub Repo
- eLinux.org Wiki: Wake from Halt - For certain versions, you can wake the Pi up by shorting pins together rather than disconnecting the power supply. However, caution is advised as these GPIO pins are adjacent to the power pins. You would want to solder a button to the pins to avoid accidentally shorting the power pins.
Need some inspiration for your next project? Check out the Pi AVR Programmer! We implement a shutdown code after programming and testing boards.
