This repository holds prototype Arduino sketches to evaluate sensor breakouts, motor drivers, and other components. These sketches generally aren't used in the real robot -- Those are included with the git repositories for the respective ROS packages.
For the software to properly identify hardware devices, udev rules should be installed. There are two udev rules for the Arduinos. Install them by copying into the /etc/udev/rules.d folder:
sudo cp /home/bro/pongrobot_arduino_sketches/udev/10-brobot-launcher.rules /etc/udev/rules.d
sudo cp /home/bro/pongrobot_arduino_sketches/udev/11-brobot-tf.rules /etc/udev/rules.d
