8 General RulesRaise your hand if you have a question. Be respectful. When I raise my hand… Share your findings with the people near you. Poke around, experiment, and have fun… Imagine, create, and play!!!
9 ObjectivesProvide a thorough introduction to the Arduino programming environment. Develop a use of simple functions to interact with the LEDs, light sensor, push button, and buzzer on the Protosnap Pro Mini.
11 Arduino LilyPad Protosnap Dev What is it? What can it do? Who cares?
12 What is it?Heart of it – ATMega328 (a $4 microcontroller) Open Source High tolerance for ESD and “bad” electronics practices… Provides easy way to interact with a computer physically – a.k.a. physical computing
13 What can it do? Great for prototyping ideas Great to teach Intro to Programming Arduino (no assembly required!)Lots and lots of options!Large pads can be sew- able
16 Components, Silk Screen & Pins 16Components, Silk Screen & PinsWhat is all this???Vibe Motorthe BrainATmega328RGB LEDTemp.SensorSwitch / ButtonSuper important. Ask people to identify what sensor is connected to what pin later on.Light SensorLight Emitting Diodes (LED)Buzzer / Speaker
26 Understanding Input vs. Output 26Understanding Input vs. OutputReferenced from the perspective of the microcontroller (electrical board).Inputs is a signal / information going into the board.Output is any signal exiting the board.Almost all systems that use physical computing will have some form of outputWhat are some examples of Outputs?
27 Startup Arduino IDEDouble-click on either the Arduino Icon or wherever you installed (saved) the Arduino program.
28 Plug it in Plug it in. FTDI is Serial buffer, 5V, GND, reset. 28Plug it inPlug it in. FTDI is Serial buffer, 5V, GND, reset.40-50 miliAmps source3.3V system. 9 pins broken out. PWM and analogs. You can reconfigure analog ins to be outputs.

43 Save your Project Save early, Save often! Enumerate your iterations – (e.g. blink_10.adp, blink_11.adp, blink_12.adp…)
44 Concept: Analog vs. Digital Microcontrollers are digital devices – ON or OFF. An Analog signal is anything that can be a full range of values. What are some examples? Think of like a ramp or a hill.
45 Concept: Analog vs. Digital To create an analog signal, the microcontroller uses a technique called PWM.Pins 3, 5, 6, 9, 10, 11 are capable of producing an Analog OutputPulse Width Modulation (PWM)
46 Color Mixing with 3 LEDs analogWrite() Challenge 2a:How do you turn on the RED LED?Experiment with different values – what do you observe happens?How do you turn on the GREEN or the BLUE LED?
47 Color Mixing with 3 LEDs Tri-color LED The RGB LED is a Common- Anode (means the positive side of the LED is all tied to Vcc). The signal line is connected to the bottom of each LED. Don’t worry - it’s just a different method of completing a circuit!5 VPin9Pin11Pin 10
48 Color Mixing with 3 LEDs analogWrite() Challenge 2b: Experiment with different values of Red, Green, and Blue to create a couple different colors. Write down the values you used. Check these values with Challenge 2c: Create a unique lighting display that integrates a blink, fade, or a switching of colors. Be prepared to have a name for your art piece and show this to the rest of the class.
