Embedded systems and the Internet of Things
A simulated microcontroller, and an MQTT broker with sensors to subscribe to.
Two labs: a simulated microcontroller with registers, pins and timers, and a message broker with three simulated sensors you read from the terminal.

Hands-on lessons
Every lesson here is worked in a hands-on lab: a real environment with a terminal beside it, nothing to install. A free account runs every lab, with enough free credit each month to follow most lessons, and is given the basic lessons on Home; with no account you can run the Git lab and the SQL lab.

Basic lessons are given to every free account, on Home, and to every college. Full course lessons are for colleges. Labs marked as an Ubuntu VM lab are set by a teacher in a module, and their lessons start the VM for you.
