Code for the Science Hack Day 2018 Project 'The multimedia cyclist' by Nicolai and Johannes
We connected a raspberry pi to two distance sensors and a neopixel led matrix. The setup is created to be used on a bikerack to detect moving objects that come too close (typically cars). If an object approaches to close, an orange arrow is displayed, indicating that the driver should keep more distance.
Raspberry Pi:
- SonarMax ultrasound sensor wired via GPIO PINs [wiring diagram]
- output LEDs, wired via GPIO PINs
- Python code to control sensors & LEDs
