High-resolution temperature sensing at low cost is possible using only one chip attached to the PC's parallel port (Figure 1). The Dallas Semiconductor (www.dalsemi.com) DS1722 digital thermometer ...

A simple, inexpensive method for building a temperature strip-chart recorder involves a parallel port that communicates with four TMP121 IC temperature sensors (Fig. 1). The sensors communicate via ...

In most sigma-delta analog-to-digital converter (ADC) applications, the serial data transfer occurs through a serial port. A microcontroller configures the serial port as required—setting the baud ...

Any peripheral component can be controlled by the 25-pin parallel port by assigning a high & low or ON & OFF state to each pin. During the design of the project, a Super Nintendo Entertainment System ...

Most modern equipment is connected over USB, and generally speaking we’re all the better for it. But that’s not to say there aren’t some advantages to using serial and parallel ports. For example, the ...

You don’t need fancy ICs and DACs to build a sound card for a PC. As [serdef]’s build over on hackaday.io shows, all you really need is a bunch of resistors. [serdef] built a clone of a sound card ...
