Adabot Toy Robot Friend

Project Overview

A friendly, 3D-printable toy robot based on the Adafruit RP2040 Prop-Maker Feather, featuring dynamic NeoPixel animations and servo motor movements.

Bill of Materials (BOM)

• Adafruit RP2040 Prop-Maker Feather
• external NeoPixels for animations
• servo motors for movement
• and 3D printed parts for the body.

Circuit Diagram & Component Arrangement

Follow the wiring diagram below. Each component connects to specific pins on the microcontroller. Use a breadboard for prototyping and ensure all connections are secure before powering on.

Wiring Summary: NeoPixels and servo motors are connected to the GPIO pins of the RP2040 Prop-Maker Feather. The project guide details the specific pin-to-pin connections for controlling the rainbow swirl effect and servo movements.

Step-by-Step Procedure

1. Step 1 - Prepare Components: Gather all components from the BOM. Inspect for damage and verify ratings.
2. Step 2 - Breadboard Layout: Place the microcontroller on the breadboard. Arrange components for clear wiring paths.
3. Step 3 - Power Connections: Connect VCC and GND first. Ensure proper polarity for polarized components.
4. Step 4 - Signal Wiring: Connect sensors and actuators per the wiring table. Double-check pin assignments.
5. Step 5 - Upload Code: Connect USB, load the sketch, and upload. Verify serial output if applicable.
6. Step 6 - Test & Calibrate: Power on and test each function. Calibrate sensors if needed.
7. Step 7 - Enclosure (Optional): Mount in a 3D-printed or custom enclosure for durability.

Safety Notes

• Always disconnect power before making wiring changes.
• Use appropriate eye protection when soldering.
• Adult supervision is required for makers under 16.
• Do not exceed voltage ratings of components.
