BRING YOUR OWN LAPTOP !!!!

0830-1030 Hands-On Lab 2 "IoT": “Hacking with Wemos Shields, Sensors, Oleds, ...“ (Dr. Andreas Spiess, Arumba GmbH) [Technical Skill Level: Medium – Advanced (Programming)]

Abstract - Description of the lab

The goal of the lab is to get an introduction to IoT devices and show the possibilities of readily available and cheap technology to build sensors and connect them to the internet.

The heart of our workshop will be a microprocessor with built-in Wi-Fi capability. It costs less than 5 dollars in single quantities, and it has enough memory and processing power to build quite sophisticated devices. The programming environment is simple. This is why these devices are used in the worldwide Maker community to create things. In addition, we will use a “shield” with a temperature and humidity sensor and one with an OLED display to create small, but fully functional and connected devices. You do not need to solder; we did it for you!

First, you build a temperature and humidity sensor with a local display. The software will come from the internet.

Then, you change the software to create a clock using the same hardware. The device will connect itself via Wi-Fi to the internet and get the time from the worldwide NTP servers. This scenario should show how quickly you can get information to your small devices.

The third scenario is a little more advanced. You have to program your device yourself and make it monitor temperature. As soon as the temperature reaches a threshold, it should switch a lamp on the presenter’s desk. As a second possibility, you can also log the measured temperature to a cloud service called Thingspeak.

Because we will have groups of two persons, you can join as a beginner or somebody with some C++ programming experience. People with lots of IOT programming skills most probably will be bored.

Prerequisites

- Own Laptop

- Internet Connection

- You need a laptop or Mac with the Arduino IDE including the ESP8266 support installed. We will create groups of two persons. So, no worry if you do not find the time to do this preparation. Maybe you will find somebody to join. The USB cables and the hardware will be there. Here is the link to the description of the work:
