This laboratory is located in the office of ITT Group in Tallinn, Estonia.

This laboratory consists of a RGB LED module connected to the ITT IoT controller module. The module contains one RGB LED. This node can be used to create very basic MQTT systems but can also be used as a signaling part of other more complicated systems.

General knowledge of MQTT protocol: topics, brokers, subscribe, publish.

This laboratory conisists of a ITT IoT controller module connected to a RGB LED module.

This laboratory involves a WS2812B RGB LED. RGB LEDs are basically three LEDs (red, green, blue) that are built inside one shell. They include a WS2812 driver that makes it possible to use only one pin to control them.

To control WS2812B RGB LED the following libaries are used:

• ITTIoT libary - used to program the controller module.
• Adafruit NeoPixel libary - used to control the RGB LED.

The user can connect to this controller using the Distancelab environment.

At the same time one user can program the controller. But all users connected to the Distancelab MQTT broker can control the RGB LED, assuming they use the topic described in the controller program.

List study scenarios (hands-on labs), linking to the Dokuwiki pages with hands-on labs descriptions (there should be a separate page for each scenario). Classify each scenario and refer to the target group using starting keywords: * Beginners * Undergraduates * Masters * Professionals Note, assume that more professional group automatically contains less professional ones. Note - use language and as appropriate to the target group, i.e.:

  * Beginners: Elementary operations on the Arduino 2x16 LCD screen.
  * Undergraduates: Visualizing temperature and humidity on the remote screen.
  * Masters: Using power saving states to limit power consumption.

Give some information on how to access help, how to get support in case of the trouble etc.
