Very suitable for first steps is the extremely inexpensive microcontroller WMOS D1 Mini with integrated WIFI chip of the type ESP-8266EX.
This course will develop a device to record the illuminance, temperature and humidity of a room. Later the control of a fan and a heater should be possible.
Prerequisites in knowledge
In order to be able to work on this course, it is helpful to have basic knowledge in the programming of Arduino microcontroller platforms.
This course can be mastered without any problems if the following courses have been previously taken:
- Introduction to Processing (basics of programming)
- Introduction to Arduino (basics of Arduino plattform)
