| So far we have studied the characteristics of the RS-232 outputs in detail. Now it is the turn of the inputs. The standard demands that an i...
| In this third part we look at the output signals of the RS-232 interface. In order to control devices with these output signals, it is neces...
| Building radio receivers is the classic introduction to electronics, usually by constructing simple detector type receivers for medium wave...
| In this second part we concentrate on software. We take a closer look at the IOtest program presented in the first article and use simple pr...
| In the first part of this article we looked at the electrical characteristics of the USB standard. In this part we investigate the software...
| Loss-free switching, using a Field Effect Transistor (FET) and a capacitor‘s discharge function, is the base theme of this elementary circui...
| At one time or another many readers may have thought about controlling or monitoring equipment using their PC. Electronics projects using a...
| Everybody is talking about the USB. In the long term, this new serial interface could replace many of the PC interfaces that have been used...
| The USB Interface described elsewhere in this issue demonstrates that the USB may be used for DIY projects related to measurement and contro...
