Embedded Hardware Problems
Bugs are not limited to software - plain electricity can be tricky, too! Sometimes it even kills (and I'm referring to Arduinos here).
- Staying well-grounded - Why not everybody can have their own GND (ground; this is important to the health of your Arduino!)
- Sufficient power-supply - Some chips suck (power)
- Port-Power - How to not power an Arduino (via an I/O port)
- Fun with power LAN adapters (don't plug your fridge into one)
