Saturday Morning BreakfastSerial: Hacking Arduinos in Python (Swift)

Transcript

1. BREAKFAST SATURDAY MORNING SERIAL by @SwiftAlphaOne

2. Note: I’m not Ryan Gosling @SwiftAlphaOne

3. ARDUINO! Let’s talk about

4. Why are developers cuckoo for arduino?

5. SIMPLE API

6. Giraffe Add Tiger Head Tigeraffe Arduino is Open Source

7. None

8. EVERYWHERE Now Available

9. LOTS OF EXAMPLES

10. GR-R-REAT! Arduino is

11. 1 2 3 4 USB Serial Port Ground & Power

    Digital Pins Analog Pins ARDUINO 101

12. HELLO WORLD “ ”

13. Download the IDE http://arduino.cc/en/main/software

14. Wire up a LED

15. Blink 1: Arduino int led = 13; void setup() {

    pinMode(led, OUTPUT); } void loop() { digitalWrite(led, HIGH); delay(1000); digitalWrite(led, LOW); delay(1000); }

16. Prototyping in C, Hey kids! is totally fun and easy.

    “ ” - The Trix Rabbit

17. Friends don’t let Friends PROGRAM IN C.

18. THE INTERNETS? How do I talk to “ ”

19. #include <Ethernet.h> #include <SPI.h> EthernetClient client; String data = '{"foo":"bar"}';

    void setup() { Ethernet.begin({0x90,0xA2,0xDA,0x00,0x55,0x8D}); } void loop() { if (client.connect("www.someapi.com",80)) { client.println("POST /api/v1/endpoints HTTP/1.1"); client.println("Host: www.someapi.com"); client.println("Content-Type: application/json"); client.print("Content-Length: "); client.println(data.length()); client.println(); client.print(data); client.println(); } }

20. #include <Ethernet.h> #include <SPI.h> EthernetClient client; String data = '{"foo":"bar"}';

    void setup() { Ethernet.begin({0x90,0xA2,0xDA,0x00,0x55,0x8D}); } void loop() { if (client.connect("www.someapi.com",80)) { client.println("POST /api/v1/endpoints HTTP/1.1"); client.println("Host: www.someapi.com"); client.println("Content-Type: application/json"); client.print("Content-Length: "); client.println(data.length()); client.println(); client.print(data); client.println(); } } LOL

21. HORSEPOWER Limited .

22. A BETTER WAY! There must be

23. Feature Wishlist Language Agnostic Cross Platform Talks to the Internets

    Complex Processing

24. FIRMATA http://firmata.org Follow your nose!

25. from pyfirmata import Arduino from time import sleep board =

    Arduino('/dev/cu.usbmodem1411') ledPin = board.board.digital[13] while 1: ledPin.write(1) sleep(1) ledPin.write(0) sleep(1) Blink 2: pyFirmata

26. Johnny-Five ? Javascript Ruby Python

27. Cookies for breakfast!? Python ^

28. BREAKFASTSERIAL http://github.com/theycallmeswift/BreakfastSerial

29. $ pip install BreakfastSerial

30. from BreakfastSerial import Arduino, Led board = Arduino() led =

    Led(board, 13) led.blink(1000) Blink 3: BreakfastSerial
31. None

32. Feature Wishlist Language Agnostic Cross Platform Talks to the Internets

    Complex Processing

33. 
    Language Agnostic
    Cross Platform
    Talks to the

    Internets
    Complex Processing Feature Wishlist

34. Buttons, LEDs, & Sensors. “ ” Servos & buzzers too.

    Lots of new components, added by devs like you!

35. SRSLY THO, I ACCEPT PULLS http://github.com/theycallmeswift/BreakfastSerial

36. M OAR!

37. ARDUINO.IO No, really. It’s coming. Go sign up. http://arduino.io
