This is the materials for a 1 hour workshop on IoT.
Connect your Arduino to the internet.
In this workshop we will use a production quality device in a developer friendly package and connect it to the internet. We will cover the Arduino APIs for wifi and MQTT and use these to get the device to send and react on messages.
Basic programming knowledge and some Arduino experience is assumed. We will not focus much on the electronics aspects of the board, but that will be covered in the "Getting Started With Arduino" workshop.
Requirements: You will need an Arduino-kit to attend this workshop. The kit can be purchased for 300NOK at the Bitraf stand.
There are some software that you should have installed, check with the person at the Bitraf stand.
