Summary
Congratulations, you have completed your quest with your new friends, the langis and the signal! You have had quite an adventure! You battled ghosts and goblins in the form of electromagnetic waves and induced currents. You learned so much along the way about serial versus parallel data transfer; digital versus analog signals; and protocols such as UART, I2C, SPI, CAN, UDP, and TCP and their secret decoder rings! You are now armed with the knowledge you will need when integrating sensors and actuators into your real self-driving car.
In the next chapter, you will learn how to use OpenCV to detect lanes on the road, a vital skill to ensure the safe and legal operation of your self-driving car!
