IEEE Control and Systems Society Workshop on The Internet of Things, was organized by ITENAS, Bandung with speaker Prof. Dr. M. Arifuddin Sohel, Prof. Atul Negi, and Prof. P.A. Govindacharyulu from IEEE CASS Hyderabad Institute of Technology Section, India. This workshop is divided into 5 chapters, namely: Chapter 1: The Internet of Things: An Overview; Chapter 2: Internet Principles and communication technology; Chapter 3: IOT System Design; Chapter 4: API Development and Embedded programming; and Chapter 5: Cloud computing and Data analytics and IoT Product Manufacturing.
On the first day of Introduction about NodeMCU. NodeMCU an open source IoT platform. It includes firmware which runs on the ESP8266 Wi-Fi SoC from Espressif Systems, and hardware which is based on the ESP-12 module. The term “NodeMCU” by default refers to the firmware rather than the dev kits. The firmware uses the Lua scripting language. It is based on the eLua project, and built on the Espressif Non-OS SDK for ESP8266. It uses many open source projects, such as lua-cjson and spiffs.
After that, we did some experiments, such as experiment 1 Blinking on board LED on NodeMCU with Arduino programming; experiment 2 NodeMCU-Blinking external LEDs; and experiment 3 Connecting NodeMCU to Wi-Fi.
On the second day, we did many experiments in a day. But before experimenting, the speaker explained the introduction of ThinkSpeak and Blynk. ThingSpeak is an Internet of Things (IoT) platform that lets you collect and store data sensors in the cloud and develop IoT applications. The ThingSpeak IoT platform provides apps that let you analyze and visualize your data in MATLAB, and then act on the data. Sensor data can be sent to ThingSpeak from Arduino, Raspberry Pi, BeagleBone Black, and other hardware.
Meanwhile, Blynk is a Platform with iOS and Android apps to control Arduino, Raspberry Pi and the likes over the Internet. It’s a digital dashboard where you can build a graphic interface for your project by simply dragging and dropping widgets. It’s really simple to set everything up and you’ll start tinkering in less than 5 mins. Blynk is not tied to some specific board or shield. Instead, it is supporting hardware of your choice. Whether your Arduino or Raspberry Pi is linked to the Internet over Wi-Fi, Ethernet or this new ESP5266 chip, Blynk will get you online and ready for the Internet of Your Things.
Based on the explanation of ThingSpeak and Blynk, we did follow up some experiments, such as experiment 4 Introduction to Blynk App- Control of LEDs using Blynk App; experiment 5 Introduction to Cloud Storage model and data analytics through ThingSpeak-Twitter updates using ThingSpeak; experiment 6 IoT based Weather Update System; experiment 7 IoT based Waste Management; and experiment 8 IoT bassed Home Automation System.
On the last day, we did the last experiment that is experiment 9 IoT based Toll Gate System. In addition, the speakers held an IoT idea competition for all participants. We propose the idea of IoT with the theme of “Smart Transport” to improve the efficiency of public transportation utilization. The main idea that we propose is to integrate passengers with the driver of public transport so that public transport drivers can know the position of the prospective passengers. In addition, we also propose a system of behavioral information on public transport, so it can be known the number of public vehicles that are less personnel with excess.
