This project displays live traffic conditions between two locations on a physical map, using an Arduino device that gathers data from the Google Maps API and then sets the color of a string of NeoPixels — green for good traffic, yellow for slower traffic, and red for bad traffic conditions, just like online maps. It refreshes every minute to adjust the color of the LEDs as the traffic changes.
The project runs on an AdaFruit Feather HUZZAH ESP8266 programmed via the Arduino IDE, but the code should run on any ESP8266 board. Its configuration is persistent across resets, as it uses SPIFFS, which is internal flash memory on the ESP8266.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
