Re: Reading data to the Pi

Is it possible to use a portable sound card to perform the ADC, such as this?

I of course meant a waveform generator in my OP, thanks...

Reading data to the Pi

Hi

I have an oscilloscope generating a sine wave at some frequency and as a fun test with my Pi I'd like to pick up this data directly with it. Is there a way to accomplish this? I'm a beginner, so any keywords/hints would be appreciate a lot.

Cheers,
Lennie.

Thanks, I will definately try that. What are the TP1/TP2 pads?

Re: Newbie electriconics question..

My question is, will my multimeter always show +5V, regardless of what value R is? Yes, because you measure always between +5V and GND. Thanks, I will check up in the links you provided. In that case, is it even necessary for me to even have a resistor placed there, or can I simply leave it out and...

Newbie electriconics question..

Hi I have a question about electronics that is very down-to-earth. Here goes: The GPIO feature of a RPi provides a +5V pin and a 0V (GND) pin. This is just similar to a 5V battery, nothing abstract here. Now I insert a resistor of R Ohm between these two pins, so from Ohm's law I get that the curren...

Wires for GPIO pins

Hi I want to start playing around with the GPIO of my R-Pi and my bread-board, but I need some connectors for the pins. I found these wires: http://www.skpang.co.uk/catalog/images/raspberrypi/kits/IMG_0005.jpg Any enthusiast here who knows what these connector-wires are called? I'll have to buy some...

Raspberry Pi for servo-systems

Hi I read somewhere online that people use their Raspberry Pi in a servo system, e.g. to control the temperature of some container (I actually think it was controlling the temperature when brewing beer! :)). I just got my Raspberry Pi a short while ago and have it up and running, but I would like to...
