My talk for IoT Bandung - MeetUp #15 event. As software developer, I share how to improve software development process when developing for IoT device, especially Arduino.

1. IoT Bandung - MeetUp #15

5. Disclaimer
Focus my talk on Arduino

6. allow me to talk about my credentials
So, you know who’s talking in front of you :)

7. Disclaimer
I’m software developer!
here’s why…

8. Start coding in QBasic
in 1997

9. My first computer
IBM XT 286
circa 1997

10. Been coding in awesome
languages/Frameworks
QBasic, Pascal, c, C++, Java, PHP, Bash,
C#, Visual Basic, HTML, JavaScript,
Python, Objective-C, Swift
.NET, Qt/QML, Java ME/EE/SE, Android
SDK, iOS SDK, Node.js, Arduino

11. 8 years in a row

12. The first & largest iOS & OSX
developer community in Indonesia
ID-Objective-C
I’m the president of

13. 100+ Software Projects & Products

14. Good enough for me To Talk about
software development :) ?

15. Disclaimer
but I do have a bit of electronics background

16. My high school is Vocational School -
Aviation Electronics

17. I took physics Major in ITB-
Instrumentation sub major
My Final project is about smart
home - in 2003

18. As software developer, what do I
learn when developing for hardware?
Hopefully you will learn it too…

19. better “Integrated development
Environments”
As software developer, I want

20. vs
Arduino IDE
Sublime TexT
with Stino

21. vs
Arduino IDE
Visual Studio
with VS Micro

22. vs
Arduino IDE
Xcode with
embedXcode

23. Demo

24. Implement Software engineering
best practices
As software developer, I do

25. Writing thousands LoC in one
.ino file kinda sucks, right?

26. Multiple .ino files?
Still doesn’t feels right
It’s hard to reuse code

27. Arduino language is based on
Wiring framework. Arduino IDE is
based on Processing (in Java).
Arduino language is implemented in
C++
Arduino supports latest major C++
standard, C++11
DID YOU
KNOW?

28. OOP
the keyword is…
Object-oriented Programming

29. C++ is OOP Language
and…

30. OOP
Inheritance
Polymorphism
Class & Object
Constructor
Destructor
Operator overloading
Encapsulation
Composition
Message Passing
Interface
Abstraction
Method overriding
Overloading

31. So this thousands LoC in
main .ino, with the help
of OOP, can become…

32. 29 LoC (including
#includes)
Not bad, no?

33. Highly readable code
Highly modular and reusable code
Highly maintainable code
Teamwork-friendly

34. Abandon Arduino/Wiring framework!
If you wanna really go full-pledge OOP for Arduino development,

35. Let’s adopt…
COSA
https://github.com/mikaelpatel/Cosa

36. void
setup()
{
pinMode(13,
OUTPUT);
}
void
loop()
{
digitalWrite(13,
HIGH);
delay(1000);
digitalWrite(13,
LOW);
delay(1000);
}
#include
"Cosa/OutputPin.hh"
#include
"Cosa/Watchdog.hh"
OutputPin
ledPin(13);
void
setup()
{
Watchdog::begin();
}
void
loop()
{
ledPin.on();
delay(1000);
ledPin.off();
delay(1000);
}
vs
Arduino Cosa

37. Demo

38. Software Design pattern
Implement

39. Software Design Pattern
Adapter
Facade
Singleton
Decorator
Filter Observer
State Machine
Builder
Flyweight
Factory
Composite
MVC DTO
DAO
Memento
Mediator

40. Do in Software as much as possible
As software developer, I will

41. Still swiTch off your
raspberry Pi manually,
without clean shutdown?
Let’s take a look this case

42. Let’s create intelligent Shutdown button

43. As hardware engineer, you’ll create this

44. Or this…
Pi Supply circuit

45. I’ll do this…

46. And a bit of code

47. Arduino Pro Mini $2
Relay module $2
Cables + switch $0.5
Total $4.5
Total Cost

48. Or you can buy one of these modules…
Mausberry $14 Pi Supply €15

49. Leverage Cloud as much as possible
As software developer, I will

50. MQTT MQTT
Web app
MQTT Broker
Data storage & analytics
Example scenario
MQTT
Web Socket
Device
Web dashboard
Smartphone
Cloud

51. MQTT MQTT
Web app
MQTT Broker
Data storage & analytics
Real example -
our HomeX Smart Home Platform
MQTT
Web Socket
HomeX Smart Stuff
HomeX Dashboard
HomeX App
HomeX Cloud

52. App & Lamp Adapter
Prototype Demo

53. App & Lamp Adapter
How to setup
Demo video: https://www.youtube.com/watch?v=NWaJ2y_41W4

54. Demo

55. Create good UI/UX Mobile & Web apps
for controlling/Accessing IoT Device
As software developer, I will

56. Sample Mobile app - our HomeX

57. Sample Web app - our HomeX Dashboard

58. Sample Web app - our HomeX Dashboard

59. CLOSING…

60. Electronics + Software Development Skill =
Awesome!

61. IoT development will breed A new type of engineer,
expert in electronics while fluent in software
development
I believe…
