Multicolor signal light with beeper for ROS by Gal Pavlin
When debugging algorithms in an autonomous vehicle a light that can show algorithm state in real time was proven to be effective for easier debugging and additional insight to what is going on in the code.
Because all existing signal light were either to bulky or too expensive we decided to build our own. It was actually quite simple with few key elements:
- 3x RGB LED strip
- STM32F0 microcontroller with native USB support
- Beeper
