In this instructable I'm going to show you how to make a Arduino device that gets traffic data from the Google Maps API and displays it to a screen and will also set the colour of a RGB LED.
The project runs on an Wemos D1 Mini (ESP8266) programmed via the Arduino IDE and costs roughly $10 in total to make.
The Arduino Traffic Display in this instructable will have the following features:
The code should run on any ESP8266 board, but the small one with only a couple of GPIO pins will not have enough pins for the display and RGB led.
First thing we need to do is put together the hardware for the project You'll need the following
You then need to assemble it as shown in the wiring diagram.
