The NodeMCU is an Arduino-compatible development board based on the ESP8266 chipset. Using the NodeMCU, you can connect to the Internet via WiFi and this provides you with a huge potential to write interesting apps. One of the things you can do is to connect to a REST service, such as a weather Web service and download the latest weather information. With the information downloaded, how do you display it? One fun project would be to connect the NodeMCU to a dot matrix display, and you can then dynamically display the weather information using the dot matrix display.
We will cover how to do this in the IOT104 - Programming Internet of Things (IoT) using Arduino course. Click the link below to check the schedule for this course.
