Parallel Port, Lamp Faders, RF Transmitters
Parallel Port Relay Interface. Below are three examples of controlling a relay from the PC's parallel printer port (LPT1 or LPT2). Figure A shows a solid state relay controlled by one of the parallel port data lines (D0 D7) using a 300 ohm resistor and 5 volt power source.Arduino Controlled Light Dimmer: 16 Steps instructables
If you could care less about the theory, but just want the software, go to the next step The way to use an AC dimmer fader is quite simple once you understand the basics: In AC the power fed to the lamp is directly related to the total surface of the sinuswave, the lamp can be regulated by only allowing a predictable part of that sinuswave to flow through the lamp.Simply Automated Plug In Controller (Lamp) Modules ...
