There are some down sides to a protection diode:
- All diodes have a voltage drop, meaning 9V on one side will drop to about 8.5V on the other. So your 9V wall wart just became 8.5V.
- Diodes have a current rating. If you try to suck 1A (1 amp) through a 0.1A (one hundred mili-amp) rated diode, the diode will quickly heat up and fail. For reverse protection, we recommend a 1A 1N4001 diode. These are dirt cheap and very common.

This is a series of lectures written for those with mild electronics background (aka Sophomore in Electrical and Computer Engineering) to learn about the wild world of Embedded Electronics. I assume only that you know what electricity is and that you've touched an electrical component. Everything else is spelled out as much as possible. There is quite a lot here so take your time! It is also my intention to get book-hardened EE's students to put down the calculator and to plug in an LED. Remember, if it smokes, at least you learned what not to do next
time!
