General RulesRaise your hand if you have a question.Be respectful.When I raise my hand Share your findings with the people nearyou.Poke around, experiment, and have fun Imagine, create, and play!!!
ObjectivesProvide a thorough introduction to the Arduinoprogramming environment.Develop a use of simple functions to interactwith the LEDs, light sensor, push button, andbuzzer on the Protosnap Pro Mini.
Arduino LilyPad Protosnap DevWhat is it?What can it do?Who cares?
What is it?Heart of it – ATMega328 (a 4 microcontroller)Open SourceHigh tolerance for ESD and “bad” electronicspractices Provides easy way to interact with a computerphysically – a.k.a. physical computing
What can it do?- Great for prototypingideas- Great to teach Intro toProgramming Arduino(no assembly required!)- Lots and lots of options!- Large pads can be sewable
Who cares?Hackers / !!

Understanding Input vs. OutputReferenced from the perspective of the microcontroller (electrical board).Inputs is a signal / informationOutput is any signal exiting thegoing into the board.board.Almost all systems that use physical computing will havesome form of outputWhat are some examples of Outputs?
Startup Arduino IDEDouble-click on eitherthe Arduino Icon orwherever youinstalled (saved) theArduino program.

How are Analog Pins reallyidentified?Digital Pins are numbered 0 to 13.Analog Input Pins are A0 to A5.A0A1A2A3A4A5 14 15 16 17 18 19
Alright? Let’s blink!Challenge 1a – Blink multiple LEDsPlan out a pattern – can you make it?Challenge 1b – Blink to mimic a heartbeatChallenge 1c – Multiple LEDS – KnightRider style
Save your Project Save early, Saveoften! Enumerate youriterations – (e.g.blink 10.adp,blink 11.adp,blink 12.adp )
Concept: Analog vs. DigitalMicrocontrollers are digital devices – ON or OFF.An Analog signal is anything that can be a fullrange of values. What are some examples?Think of like a ramp or a hill.
Concept: Analog vs. DigitalTo create an analog signal, themicrocontroller uses a technique calledPWM.Pins 3, 5, 6, 9, 10, 11 are capable of producing anAnalog OutputPulse Width Modulation (PWM)
Color Mixing with 3 LEDsanalogWrite()Challenge 2a:1) How do you turn on the RED LED?2) Experiment with different values – what do you observehappens?3) How do you turn on the GREEN or the BLUE LED?
Color Mixing with 3 LEDsTri-color LEDThe RGB LED is a CommonAnode (means the positive sideof the LED is all tied to Vcc).5VThe signal line is connected to thebottom of each LED.Don’t worry - it’s just a differentmethod of completing a circuit!Pin9Pin11Pin10
Color Mixing with 3 LEDsanalogWrite()Challenge 2b:Experiment with different values of Red, Green, and Blueto create a couple different colors.Write down the values you used. Check these valueswith www.colorpicker.comChallenge 2c:Create a unique lighting display that integrates a blink,fade, or a switching of colors. Be prepared to have aname for your art piece and show this to the rest of theclass.
