The document provides an overview of Arduino, an open-source electronics platform for interactive projects, detailing the setup, programming, and hardware aspects involved. It covers the workflow for creating projects using the Arduino IDE, including code writing, uploading, and debugging, along with a description of various projects that can be built using an Arduino starter kit. Additionally, it shares personal experiences and links to further resources for enthusiasts looking to explore Arduino projects.
Get your hands dirty with Arduino
- 1. Get your hands dirty with Arduino Savio Dimatteo Heidelberg Web Enthusiasts Meetup - 10 Dec 2014
- 2. Arduino
- 3. Arduino from http://arduino.cc “Arduino is an open-source electronics platform based on easy-to-use hardware and software. It's intended for anyone making interactive projects.” IDE + Board
- 4. Making a project 1. wire components on a breadboard and connect them to arduino I/O pins
- 5. Making a project 2. write code into the IDE to read/write from/to Arduino pins
- 6. Making a project 3. compile & upload code into a chip on the board machine code
- 7. Many Models
- 8. Many Models
- 9. Many Specs Parameters ● Input voltage ● CPU Speed ● # Analog I/O pins ● # Digital I/O pins ● FLASH capacity ● EEPROM capacity ● SRAM capacity ● USB interface ● UART
- 10. Many Specs Parameters ● Input voltage Cost: ~4€ ● USB interface ● UART
- 11. Arduino UNO Cost: ~25€
- 12. Arduino shields
- 13. Arduino IDE
- 14. Arduino code ● language is an implementation of Wiring ● syntax looks like a mix of Java/C/C++ ● feels almost like a scripting language... ● code preprocessed into C++ ● compiled and linked against Arduino libraries ● machine code into a file ready for upload
- 15. Typical workflow ● write code ● compile ● connect Arduino via USB ● upload ● see if it works
- 16. Debugging ● write code using Serial.print(...) ● compile ● connect Arduino via USB ● upload ● open serial monitor ● see if it works, check serial monitor output
- 17. Get started http://www.google.com http://www.instructables.com/ http://playground.arduino.cc
- 18. Starter kit (~100€) ● Arduino Projects Book ● Arduino UNO ● USB cable ● Breadboard ● Wooden Base ● 9v battery snap ● Wires ● Photoresistors, potentiometers, pushbuttons, sensors, LCD display, LEDs, Transistors, Optocouplers, Piezo, Small Motors, Diodes, Resistors...
- 19. Blink
- 20. Uploading blink
- 21. Blink uploaded
- 22. Hello, World!
- 23. Hello, World!
- 24. Projects book ● 01 GET TO KNOW YOUR TOOLS an introduction to the concepts you'll need to use this kit ● 02 SPACESHIP INTERFACE design the control panel for your starship ● 03 LOVE-O-METER measure how hot-blooded you are ● 04 COLOR MIXING LAMP produce any color with a lamp that uses light as an input ● 05 MOOD CUE clue people in to how you're doing ● 06 LIGHT THEREMIN create a musical instrument you play by waving your hands ● 07 KEYBOARD INSTRUMENT play music and make some noise with this keyboard ● 08 DIGITAL HOURGLASS a light-up hourglass that can stop you from working too much ● 09 MOTORIZED PINWHEEL a colored wheel that will make your head spin ● 10 ZOETROPE create a mechanical animation you can play forward or reverse ● 11 CRYSTAL BALL a mystical tour to answer all your tough questions ● 12 KNOCK LOCK tap out the secret code to open the door ● 13 TOUCHY-FEEL LAMP a lamp that responds to your touch ● 14 TWEAK THE ARDUINO LOGO control your personal computer from your Arduino ● 15 HACKING BUTTONS create a master control for all your devices!
- 25. What did I do with Arduino
- 26. Got rid of IDE ● mkdir blink && cd blink && ino init ● vim src/sketch.ino ● … edit … save ... ● :!ino build ● :!ino upload ● :!ino serial (optional)
- 27. My first project
- 28. Trampolino ● hardest hardware part: insert a straw at the base of a bottle
- 29. Trampolino ● hardest hardware part: insert a straw at the base of a bottle ● hardest software part: try to be precise when pouring the same amount of water...
- 30. Problem ● water doesn’t flow at a constant rate!
- 31. Problem How many seconds to pour for, to get the same unit of water out of the straw?
- 32. Possible Solution I. measure flow rate II. estimate pressure
- 33. Detecting water void setup() { pinMode(9, INPUT); } void loop() { if (digitalRead(9) == LOW) { // water detected! } }
- 35. Curve fitting
- 38. On Facebook...
- 39. Conclusions ● very easy to get started ● time consuming ● exciting ● expensive ● generally not dangerous
