In this chapter, we learnt how to work with actuators. We started working with a DC motor; then we learnt how to control its speed using the PWM method. Next, we learnt how to use Arduino interrupts and why they are important. In the end, we worked with a servo motor and understood how to move a servo motor at specified angles.
As a conclusion, we looked at a suggested drone-boat design using some motors and a radio frequency module with the Arduino. In this chapter, we already learnt how to use a DC motor and a servo motor. After reading through Chapter 10, Day 8 - Short Range Wireless Communications you will be able to use a radio frequency module with the Arduino. Thus, we come to the end of our short journey of learning to use actuators.
In the next chapter, we will learn how to interface AC powered devices with the Arduino. AC mains are at a very high voltage and...
