17 ARDUINO-TO-RS232 COMMUNICATION
The RS232 data bus is a popular wired method for electronic devices to communicate with one another. It was originally devised in the late 1960s and is still used today in industrial programmable logic controllers (PLCs) and applications that require reliable wired point-to-point data transfer. It’s also often used to interface computers with older devices.
This chapter shows you how to interface an Arduino with the RS232 bus for data transmission and remote-control applications. You’ll learn to:
- Add an RS232 interface to your Arduino using a board or shield
- Build a PC-to-Arduino remote control that operates ...
