Summary
In this chapter, we have seen how to hook a Bluefruit LE transceiver to our robot and then use it to send and receive data. We’ve seen the robot data go to a smartphone and data go from a smartphone back to Pico on the robot.
We then took this up a level and sent formatted data to plot sensor information on the phone, allowing us to remotely visualize the robot’s state.
Finally, we used the smartphone app to control and drive the robot. In the next chapter, we will look at the PID algorithm, a neat way to tie sensor data and outputs together in a feedback loop, and we’ll use our new remote data plotting ability to tune it!
