Re: how to use the GPIOs

I would like to make some basic modules/schema that can be used in a variety of projects. First to be able to use the raspberry as controller for some appliances such as lights, shutter engines, dimmers … Later to use the raspberry as the central element for reading sensors in a home network. First ...

how to use the GPIOs

It appears to me that ther eis very little informaiton around about hardware configurations that correctly connect to the raspberry. Sure, some simple examples making leds blink and so, but nothing substantial. If I am not completely mistaken then you need quite a bit of precautions when using GPIO ...

Re: STICKY: Introduce yourself!

Hai,

I am a newbie, not much to say about myself actually, just that I have experience programming in visual basic, c sharp, fortan and a load of other languages but no hardware experience whatsoever.
