In this chapter, we dealt with ROS interfacing of embedded controller boards and single-board PCs. We started by discussing popular controller boards, such as Arduino, STM 32-based boards and Tiva C boards. In the single-board computer category, we went through Raspberry Pi and Odroid. After discussing each board, we learned about interfacing ROS with controllers and single computers. We covered LDR interfacing with the Arduino, Hello World example on the STM 32, and RGB demo on the Tiva C Launchpad. For single-board computers, we created a basic LED blink demo using ROS.

In the next chapter, we will discuss teleoperating a robot using hand gestures.
