| In a fix? Need to get a microcontroller project off the ground FAST? This article proves that an ultra-versatile microcontroller board can b...

| There are many small applications where it would be preferable to power a device directly from an RS232 (V.24) interface, avoiding a mains p...

| This circuit can be built into a power bar and used to remotely switch six socket-outlets. It is controlled via an RS232 interface and uses...

| Thanks to a special integrated circuit from FTDI Chip, computer peripherals with an RS232 interface are easily connected to a USB port. This...

| Many Metex DVMs feature a serial interface (RS232) which enables measured values to be copied to a PC for processing. Although this works ju...

| This project has been designed to interface an EIA-232 channel to an EIA-485 half-duplex bus. We should do so because EIA-485 offers more fe...

| The circuit converts an analogue voltage to its digital equivalent which is transmitted to a PC via an RS232 link.This type of circuit is us...

| Only simple materials and a little bit of skill are needed to build an RS232 switch. All that you need are two 9-way sub-D plugs with solder...

| With the help of a minimal quantity of hardware and a simple piece of software it is possible to tap into the data stream between two serial...

| This circuit represents an interface converter between the UART pins of a microcontroller (with TTL levels) and a ‘standardised’ RS232 port...
