This document provides an introduction to using Arduino microcontrollers for educational purposes. It begins with introductions among attendees. It then discusses SparkFun's focus on open source hardware and physical computing. The document provides an overview of Arduino microcontrollers and their capabilities. It walks through setting up the Arduino IDE and demonstrates some basic code examples, including blinking an LED and reading sensor input. Questions are posed to encourage experimentation. Additional educational resources from SparkFun are mentioned at the end.

- 2. Pause… Before we move any further, let’s make sure that we all know each other in this room? Please introduce yourself to the person(s) sitting in your general vicinity. Tell them a few things about yourself, maybe: – where you’re from – what you teach – why you’re here – what you hope to get out of this….
- 3. About Us At SparkFun, our focus is all about creation, innovation, and sharing information. Open Source Hardware is at the core of our business. We emphasize researching, re- mixing, adapting, making improvements, and sharing with the world!

- 8. Arduino / Microcontrollers a.k.a. Physical Computing “Arduino is a tool for making computers that can sense and control more of the physical world than your desktop computer.” A micro-controller is essentially a brain – or, think of a bunch of programmable “elves…” It is the guts of something like Vernier, Pasco, or Fourier
- 9. What can this thing do? Remember, think programmable “elves” We can use this to: - Turn on lights - Interface cameras (take photos) - Log sensor data (temp, pressure, humidity, light…) - Communicate with your PC and the internet (a.k.a. Internet of Things) - Take Science Fair to the next level…

- 11. Hardware Configurations / Connections What’s a Pin? 14 general digital input / output pins 6 analog input pins (Pins A0 – A5) Nitty Gritty: Powered off anything from 7 – 15V DC Voltage Regulator provides 5V and 3.3V Standard TTL logic – 5V is HIGH, and 0V is LOW.
- 12. Getting started • Download Arduino from: www.arduino.cc/download • Follow their directions on installation.
- 13. Startup Arduino IDE • Double-click on either the Arduino Icon or wherever you installed (saved) the Arduino program.
- 14. Plug in your RedBoard (Arduino)
- 15. Lesson #0 – Setting up Arduino 1.Setup Board –Arduino Uno 1.Setup COM Port –PC – Highest COM # –Mac – /dev/tty.usbserial-A####xXx

- 18. Anatomy of code General syntax: – Case-sensitive – Semi-colons – Curly-brackets void functionName()
- 19. Just the basics Turning an LED on and off…
- 20. Open Challenges 1) Create a heartbeat – a realistic one! 2) What is the fastest blink that your eye can detect? What is the frequency of this blink? Now, move the LED back and forth – do you see a “trail”? What are some interesting scientific investigations you can explore with this? 1) What about making a timer?? – blink the LED for 10 seconds and then stop! 2) What other ideas?
- 21. Introducing the Danger Shield What’s a Shield?

Notes de l'éditeur
- What is science? What is the nature of science? – Inquiry, Investigation, Experimentation… But, we’re past the ages of using rulers, stop watches, and old school techniques to investigate our world. How are real scientists doing it?
- Plug it in. FTDI is Serial buffer, 5V, GND, reset. 40-50 miliAmps source 3.3V system. 9 pins broken out. PWM and analogs. You can reconfigure analog ins to be outputs.
- Talk about different board types

- I’m not sure if this one works. It did not work on the Danger Shields that we had in the classroom.
- This is a new learning platform for Arduino to be released in the next few months. It integrates 5 white LEDs, an RGB LED, a microphone, light sensor, temp sensor, slider, switch, button, and two general purpose I/O ports.
