Checkpoint (due before spring break)

• A drawing of your desk pet
• A name for your desk pet
• At least one servo working
• At least one part of your desk pet 3D-printed

Hello

Today you will start working on your mid-semester project. 🙂👍 This homework will last 2+ weeks (next week you will also have some other stuff to do, so probably don't put this week's work off.)

• When in doubt, google the part! 🙂👍
• Don't forget what we've learned about making boxes, using screws and captive nuts, etc.
• ⚠️ Do not "short" (accidentally connect) the metal pads and pins on these little boards. Best bet is to solder on header and plug into a breadboard .

Parts

• STEMMA Wired Tactile Push-Button Pack - 5 Color Pack
• Adafruit Metro Mini 328 V2 - Arduino-Compatible - 5V 16MHz
• Adafruit BH1750 Light Sensor - STEMMA QT / Qwiic
• Adafruit I2C Stemma QT Rotary Encoder Breakout with NeoPixel
• Continuous Rotation Servo
• Breadboard-friendly 2.1mm DC barrel jack
• 9V battery holder with switch & 5.5mm/2.1mm plug
• 4 x AA Battery Holder with 2.1mm Plug and On/Off Switch

HINT

• You can print to the Serial Monitor using Tools -> Serial Monitor

Spec

• A-
  • (Not Submitted) Before soldering anything, verify you can connect to the dev board and upload & run the Arduino Blink program.
    • You may need to select Tools -> Port -> COM ??.
  • (Not Submitted) ⚠️ Disconnect the dev board from USB-C before soldering!
  • (Not Submitted) Solder male header to the dev board and plug into your breadboard (make sure is "straddles the ravine").
  • (Not Submitted) Get a button working to turn on the built-in LED.
  • (Not Submitted) Get a button working to turn on an external LED.
    • NOTE: You must use a resistor in series with the LED (https://forum.arduino.cc/t/why-do-i-need-a-resistor-when-using-leds-on-an-uno/366861)
  • (Not Submitted) Get the knob working (it also has a RGB led 🙂)
    • https://www.adafruit.com/product/4991
    • Note: Make sure to solder the big pads too!
  • (Not Submitted) Get the big continuous rotation servo working.
    • How to wire a servo to an Arduino with external power.
      • More details.
  • Make any sort of robotic desk pet.
  • Use one light sensor and at least one servo.
• A
  • Make your robotic desk pet fabulous.
  • (Deadline: before spring break) Design a carrier board for your Metro Mini in KiCad and send to Jim (make sure it works on OSH Park)
• A+
  • Make your robotic pet transcendent.
    • It should seem cute and alive. 🙂👍
