With this tiny dongle there are still a lot of possible projects possible and things to learn:

1. Sending and receiving data via WiFi. Running a Web Server, posting data to other servers. Using TCP or UDP protocols
2. Usage of buttons and interrupts in micro controllers
3. Controlling an WS2812B LED. This one is RGB so you can display lots of different colors
4. Measuring Temperature - the included temperature probe is quite precise so you can measure and post temperatures online
5. Managing Heat - the device consumes ~100 ma when turned on, which produced enough heat to influence the temperature measurement. So using deep-sleep functionality this can be controlled
6. Various mashups of those functionalities are possible
7. There are 4 extension ports, 3.3v, 5v and GND outputs - to connect external sensors, actuators and display (more on this in a later update)
