Arduino Mega + LIDAR-Lite 2 Laser

Laser Range Sensor


I2C protocol5 volts

Sensors are an important component of building a robot. Knowing the distance to an obstacle in front of the robot is extremely useful. For example to avoid a collision. An electronic compass and GPS is not sufficient to avoid a collision. I have thus experimented with several distance proximity sensors.

The Arduino Mega has pins 20 and pin 21 for the i2C SDA and SLC connectors.
