Hi guys,
I'm completely new to Teensy or actually building any circuits but with the help of internet I am working on a control panel (~20 2-position switches, few buttons and ~20 LED) with Teensy 3.6.
Tho most of the things needed I already have planned, there is however one I can't find the correct answer for. Every single I found apply to external power.
The board will get power from USB port only, I have no intentions to add any external power supply. However, I would like to be able to turn on/off the entire panel with one mechanical 2-position switch.
Is it possible when using USB only? If yes, could you tell me what pins I should use and how exactly step-by-step connect it?
Regards
Diego
