Finally, we come to the end of this chapter and we have built our own IoT-enabled robotic car which can be controlled remotely. The car has all the basic moves like forward motion, backward motion, and it is also capable of taking turns. We also learnt about PWM and how it helps to control the speed of an analog DC motor using digital signal.
In Chapter 9, Security in IoT, we will study the most important aspect of IoT security of an IoT ecosystem. Without a secure and protected ecosystem our services and products will be vulnerable to hacking and cyber-attacks which can cause huge losses to people and business. So let's get ready to secure your IoT ecosystem in Chapter 9, Security in IoT.
