Arduinocan work as the heart of the PLCs that we are going to build. The basic type of Arduino, Arduino UNO, is best for learning basic concepts behind the PLCs as well as implementing prototypes with a combination of hardware (inputs, outputs) and software (Arduino software and libraries like plcLib and Modbus).
In the previous chapter, you learned about how to prepare your development environment with various hardware and software. In this chapter, you will learn more about Arduino UNO, Arduino Ethernet shield, and Arduino WiFi shield.
