Now, despite being superseded by USB, many peripherals still make use of this protocol for internal communication between components, to transfer data, and to update firmware. For electronics hobbyists, RS232 is a very useful protocol for debugging and controlling other devices while avoiding the complexities of USB.

The two scripts in this example allow for the control of the GPIO pins to illustrate how we can remotely control Raspberry Pi using the serial port. The serial port can be connected to a PC, another Raspberry Pi device, or even ...
