PC-Audio-Output as an Interface
Today the most interfaces to the PC are USB based.
A few days ago I stumbled over the idea to use the soundcard audio-output as programming interface :
The connector is simple and standard, you need only two wires – a good idea for a cheap and simple interface for programming – but not only … let’s extrapolate this a bit:
You could use it also for control purposes, for example for the PlotRobot.
- via a wire – a wire remote control – as a first step
- via infrared – like in your TV-remote control
- via sound – why not? – maybe with nice tones ..
Further extensions are thinkable – maybe the PlotRobot can send himself back to the PC – maybe you can use the microphone-input in the same way …
Would be funny listening to the PlotRobot and the PC tweeting to each other 🙂
