In the previous chapters, you learned a lot about the fundamentals of PLCs and their applications in industrial process automations. Further, you learned about some Arduino-based industrial PLCs available in the market, which exposed core functionalities of the Arduino with additional hardware layers.

Grove Base Shield Basics

Grove Base Shieldis the same size as an Arduino UNO board and can be used to create another level of hardware interface with Arduino pins. As you can see in Figure 4-1, there are only three active components soldered on to the board (two resistors ...
