- 2. 2 WHAT IS ARDUINO? Arduino is an open-source electronics platform based on easy-to-use hardware and software. It’s intended for anyone making interactive projects.
- 3. 3 HISTORY Arduino project was made by a team of students and teachers from the interaction design school of Ivrea. http://interactionivrea.org/ en/index.asp
- 4. 4 Gianluca Martino, David Mellis, David Cuartielles, Tom Igoe, Massimo Banzi et Nicholas Zambetti. HISTORY
- 5. 5 The inspiration come from processing, a programation language develloped in 2001 by Casey Reas and Ben Fry, two students of John Maeda from M.I.T.. HISTORY
- 6. 6 ADVANTAGES * Simple to use * Cheap * Open Source * Multi-plateforms
- 7. 7 PHILOSOPHY & COMMUNITY Arduino project is based on a principle of open Source which has help it to have a quick developpement thanks to a community who work on the software and hardware. There are several tools to share and learn: - Blog (http://blog.arduino.cc/) - Forum (http://forum.arduino.cc/) - Wiki (http://playground.arduino.cc/)
- 9. 9 ARDUINO = TWO THINGS Hardware for prototyping Software for programing
- 10. 10 PLATEFORM (HARDWARE) Arduino is like a brain who going to make logical connections between an action and a sense. For example, if we read a text: The eyes (INPUT) see the image of the text, the brain (ARDUINO) read and make the interpretation for the mouth (OUTPUT) who’s make the sound of the reading text.
- 11. 11 PLATEFORM (HARDWARE) Different type of card
- 12. 12 PLATEFORM (HARDWARE) input USB power
- 13. 13 PLATEFORM (HARDWARE) Processor
- 14. 14 PLATEFORM (HARDWARE) +5V and +3,3V digital PWM ground - analog digital
- 15. 15 PROGRAMMATION (SOFTWARE) Go on the website Arduino
- 16. 16 PROGRAMMATION (SOFTWARE) Download the software
- 17. 17 PROGRAMMATION (SOFTWARE) Run the installer if you computer need it, download FTDI drivers.
- 19. 19 FIRST STEP Software
- 20. 20 FIRST STEP Choose the good card.
- 21. 21 FIRST STEP Choose the serial port
- 22. 22 FIRST STEP Select example “Blink”: examples/ Basics/ Blink
- 23. 23 HOW WORKS A CODE? Like a recipe
- 24. 24 HOW WORKS A CODE? ingredients tools preparation
- 25. 25 A LITTLE BIT OF LANGUAGE pinMode() – Define your pin as an input or output. digitalWrite() – Send a binary value (high/low) to a pin. digitalRead() – Read a binary value (high/low) from a pin. analogRead() – Read a analogic value (from 0 to 1024) from a pin. analogWrite() – Send a analogic value (from 0 to 255) to a pin. delay() – allow a to make a break, arduino clock count in milliseconds.
- 26. 26 FIRST INTERACTION Plug your led like the image.
- 27. 27 HOW TO PLUG A LED? Led have a way to plug it, one negative leg and one positive leg. Three ways to find the good way: - Usually longest leg is + - Truncate side is - - The biggest part inside the led is - + + - -
- 28. 28 int led = 13; void setup() { pinMode(led, OUTPUT); } void loop() { digitalWrite(led, HIGH); delay(1000); digitalWrite(led, LOW); delay(1000); } FIRST INTERACTION Try to change delay.
