You can now apply this information to build innovative moving devices such as a remote-controlled reconnaissance boat that can be guided into dark, underground drainage systems in smart cities. The primary focus of this section will be to inspire you by giving you an advanced idea that you should try out on your own.
Sounds exciting, right? Take a look at the diagram below. You will get an idea of how we can build a remote-controlled boat using a DC motor and a servo motor. You would also need additional devices such as a radio frequency module for operating the motors remotely. We will learn Radio Frequency-based communications in Chapter 10, Day 8 - Short Range Wireless Communications.
The inspirational preceding example uses one DC motor and a servo motor. The DC motor has to be fitted to drive the boat's propulsion system...
