Weekly Progress
RS-232 is a telecommunications standard for binary serial communications between
devices. It supplies the roadmap for the way devices speak to each other using serial ports.
For example, a computer and microprocessor, barcode scanner, RFID scanner. RS-232
sets acceptable voltage and signal levels. It also specifies protocols for the control
information pass between devices, which includes such event such as begin or end of a
data. RS-232, or serial ports, is now used almost exclusively for dial-up modems. Other
devices, like mice, that used to use serial ports, now make use of newer USB and Fire wire.
Ports.RS-232 will eventually become an obsolete standard. The microcontroller is used for
RS-232 interface with a computer.

Engineering Analysis
Strong Point
- Easy to programing
- High-speed data transmission.
- Use a few signal cables.
Weak Point
- Need the driver to control a device.
- Difficult to use when compared USB.
Next Week Job
- I will learn programming about RS-232.
