Part 1: Your Pico’s Pins
Vocabulary
Fill in the physical pin number (or numbers) for each one from the pinout figure, not just what it means.
| Word | Pin #(s) | What it means |
|---|---|---|
| GPIO pin | ||
| PIO | ||
| ADC | ||
| VBUS | ||
| VSYS | ||
| GND | ||
| RUN | ||
| Brownout |
Careful reading
- Your Pico's GPIO pins start counting at the number instead of the number .
- The pin numbering skips from GP22 straight to GP26_ADC0. Why is there a gap?
- Most of your Pico's pins can work as either an input or an output. What decides which one a pin actually is?
Part 2: Electronic Components
The chapter shows a figure with nine common components, each labeled with a letter. Find that figure, then fill in the letter for each component, say whether it’s mainly an input, an output, or a connector, and what it actually does.
| Component | Letter | Input, output, or connector? | What does it do? |
|---|---|---|---|
| Resistor | |||
| Jumper wire | |||
| LED | |||
| PIR sensor | |||
| Breadboard | |||
| OLED display | |||
| Piezoelectric buzzer | |||
| Potentiometer | |||
| Push-button switch |
- A PIR sensor is a kind of input device called a sensor. What does this particular sensor detect?
- A potentiometer can actually work as two different kinds of component. Name one of them.
Part 3: Reading Resistor Colour Codes
This part is a quick, useful skill, not something to stress over.
The chapter's example resistor has two orange bands and one brown band. The two orange bands give the digits and . The brown band means multiply by . Put together, that resistor is ohms.
- What colour bands would a 100 Ω resistor have?
- If you wanted the cheapest resistors, what colour tolerance band would you look for?
Wrap-up: 3-2-1
