## How to tell the components in the kit apart
Since they're not labeled, you have to go off of a few clues:
- Generally, the number of parts is the best clue. You usually have the exact amount or one more.
- Capacitors (C) have a brown body with no letters. They come on white strips
- Resistors (R) have a white bottom and black top, with white digits/letters explaining their value. They come on white strips.
- `471` means `47` with `1` 0, so 470 ohms
- `01C` means 10Kohms with 1% tolerance, no idea why
- LEDs (D) have clear tops and come on black strips. The diode direction is indicated by the trangle on their bottom side.
- 0603 LEDs are very hard to solder. Don't fret if they don't work first-try
- The big ICs are labeled with a number similar to their model number
- The rest should be guessable from the part's footprint

- [2022 version] There is a pull-up resistor missing for the button. A 10kOhm THT resistor can be soldered from the backside of the bin header to the battery holder. - [2022 version] There is a pull-up resistor missing for the button.
