Sign-off
Fill this in once your circuit is built. It’s kept at the top so your teacher can find it quickly.
| Check | Neighbor | Teacher |
|---|---|---|
| LED circuit matches exemplar 1 |
Fill this out as you build Project 1.1: Wiring Three LEDs. Check off each stage as you finish it. You can write your answers in your own words: you do not need full sentences.
Stage 1: Power and Wire Color
- What color wire carries 3V3 power? What color carries ground? What color carries a GPIO signal?
- Which physical pin feeds your power rail? Which feeds your main ground rail?
- Which physical pin feeds your spare ground rail?
Stage 2: The LED Circuit
Fill in the physical pin number and GPIO name you used for each LED.
| LED | Pin # | GPIO name |
|---|---|---|
| LED 1 | ||
| LED 2 | ||
| LED 3 |
- You trimmed your LEDs' legs for neatness, so leg length no longer tells you which lead is which. Name the two things on the LED itself you can check instead.
Wrap-up: Notice and Wonder
- Notice: write 2 things you noticed while building today.
- Wonder: write 2 questions you have.
Workmanship Rubric
This is the baseline every circuit is expected to meet, not a scale for who tried hardest. Going beyond this is its own reward, separate from this grade.
| Criterion | Possible | Earned |
|---|---|---|
| Passed sign-off within the first or second check | 1 | |
| Power rail wired correctly (pin 36) | 1 | |
| Main ground rail wired correctly (pin 38) | 1 | |
| Spare ground rail wired correctly (pin 18) | 1 | |
| All 3 LEDs present and connected | 1 | |
| LEDs wired with correct polarity | 1 | |
| LEDs connected to the correct GPIO pins | 1 | |
| LED legs trimmed short and neat | 1 | |
| Resistor leads trimmed short and neat | 1 | |
| Wires lie flat: no more than 2mm above the breadboard | 1 | |
| Correct wire color used throughout (red, green, white) | 1 | |
| Pico fully and correctly seated in the breadboard | 1 | |
| Total | 12 |
