• Circuts are designed in stages, components are usually grouped for functionality. For instace, the amplification stage.

• Find voltage/ground with continuity test on multimeter (speaker icon)

• Pullup resistors prevent short circut by eliminating floating switches

• Switches tend to bounce

• To debounce we smooth it out with a capacitor, or account for bounce in software

• To chain multiple parameters in a single if statement, use && for and,

  for or.

• Check out Adafruit.io for data visualization

Wall Warts

• DC, VDC Out is ideal

• RoHS Compliance means no lead!

Switching vs Linear

• Switching: Regulated, has choppers, voltage is maintained, preferable.

• Linear: Not regulated, very unsophisticated, heavy, big magic block of metal, not preferable.
