For power led indication, use in conjunction with Delay Timer connected to GPIO14 (https://easyeda.com/lynxlabeling/delaytimer).

Note: this circuit is connected to an N-channel Fet, which pulls GPIO3 pin low when activated. Add 'dtoverlay=gpio-shutdown' to /boot/config.txt file to use. For info, see:
