Agenda

1. Welcome!

   • What is IDeATe?

   • What is Physical Computing? What is a kinetic system?

   • Project focus: marble machines

   • Unspoken prerequisites.

   • 16-223 is a good portal for the IDeATe Physical Computing Minor

2. Administrative

   • Pandemic concerns.

   • Enrollment and waitlist.

   • Course site: https://courses.ideate.cmu.edu/16-223

     • Daily log pages (like this one): Daily Agenda Logbook

     • 16-223 Student Work

     • Canvas and Canvas Calendar

   • Laser cutter qualification: see IDeATe Laser Cutter Policies

   • Attendance and tardiness policies.

   • Electronic device policies.

   • Physical Computing Lab

     • Card access

     • Physical Computing Lab use and abuse

     • We are sharing the room with six other classes (see IDeATe PhysComp Lab Calendar)

   • Computing Needs

   • Office hours: TBD. Please answer my office hours poll.

   • Name tags and photos.

3. In-class

   1. Mutual introductions, In-Class Exercise: Interview Game.

   2. Brief introduction to the Raspberry Pi Pico and CircuitPython.

   3. Each person pick up a Pico and a USB cable.

   4. Installing the Mu Python Editor.

   5. Crash course in CircuitPython basics.

   6. Please return the Pico and cable if you don’t expect to be continuing in the course.

   7. Introduce short programming assignment.

New Assignments

1. Please write a variation of the pico_blink.py program (below) to produce a rhythmic pattern of your choice to be demonstrated at the start of the next class.

2. Please complete the CKS Fall 2021 Skill Survey if you haven’t already. This should just take a few minutes.

3. Please fill out the office hours poll if you haven’t already.

4. Please complete laser-cutter training as soon as possible if you have not already done so. Note that we will soon have assignments requiring access, and you are responsible for ensuring your qualification. There are three parts:

   • asynchronous online course: BioRAFT Laser Cutter Safety

   • scheduled online course: BioRAFT Fire Extinguisher Training

   • asynchronous video training: IDeATe Laser Training Part 1, IDeATe Laser Training Part 2

   For more details: IDeATe Laser Cutter Policies, IDeATe Laser Cutter Overview

# pico_blink.py

# Raspberry Pi Pico - Blink demo

# Blink the onboard LED and print messages to the serial console.

import board
import time
from digitalio import DigitalInOut, Direction, Pull

#---------------------------------------------------------------
# Set up the hardware: script equivalent to Arduino setup()
# Set up built-in green LED
led = DigitalInOut(board.LED)  # GP25
led.direction = Direction.OUTPUT

#---------------------------------------------------------------
# Run the main loop: script equivalent to Arduino loop()

while True:
    led.value = True
    print("On")
    time.sleep(1.0)

    led.value = False
    print("Off")
    time.sleep(1.0)
