1) The document introduces Alwin Arrasyid and discusses his role as an IoT Software Lead. 2) It provides a gentle introduction to IoT, defining it as a network of physical objects with embedded electronics, software, and connectivity to exchange data for intelligent applications and services. 3) The document discusses using JavaScript for IoT development as it lowers the language barrier by not requiring developers to first learn C/C++ before programming microcontrollers.

3. IoT Software Lead

4. IoT? What?
A gentle introduction

5. Internet of Things
Network of physical objects with embedded electronics,
software, connectivity, and people to enable connectivity
to exchange data, for intelligent applications and
services

6. Internet of Things
•Ranges from measuring things in physical world to
building devices, and all the way to building end
application
•Brings people with various background of expertise
together

7. SmartGallon
Smart drinking and water monitoring
solution.

17. Why JS?

18. Languages for the Things
And many more...

19. Frameworks of the Things
ESP-IDF
And many more...

20. So, Why JS?
the answer is...

21. Lowering the language barrier

22. Lowering the language barrier?
•You don't need to learn C / C++ before learning how to
program a microcontroller
• You can learn C / C++ afterwards

24. Espruino
•Is a platform for developing things with JavaScript
•Has its own official boards
•Has its own Web IDE and graphical editor
