[Project] An Arduino Linkbot Siren System as Police Car, Ambulance, or Fire Truck


Linkbot is a reconfigurable modular educational robot. Arduino board is a popular open-source single-board microcontroller. Barobo Arduino provides a user-friendly solution for making and building in the physical world, and integrating sensors into Linkbot systems using Arduino.

In this project, a Linkbot and Arudino are used to build a police car, ambulance, or fire truck with a flashing light. The robot moves with a blinking RGB LED and siren of police car, ambulance, and fire truck. The entire system is controlled by a program with only 19 lines of code!
