Adafruit's TV B-Gone kit (http://www.adafruit.com/products/73) is such a simple device, yet so effective and provides plenty of silly joy.
Here is what I would like to achieve: Connect a Pi to the network and run webiopi on it. One button let's you take a picture to see if the TV is on, the other button then let's you turn off the TV.
I am struggling with the way I can activate the kit. From the description (http://learn.adafruit.com/tv-b-gone-kit/design-notes), it says, that
"There is one button. Pressing & releasing will start the kit to emit IR codes. The button is actually hooked up to the microcontroller's reset pin and tells the chip to reset. When the chip resets it automatically emits all the codes in its library. When it's done it goes into a very-low-power sleep mode and awaits another button press. "
The schematic further below on the same page shows how the button S1 connects RST to GND in order to activate the TV B-Gone. I might have missed something, but it seems, that the Pi can only send 3.3V or nothing under webiopi (or in general) and not connect something to GND. So I am thinking of putting in a 3V relay to connect RST to GND.
Is my thinking correct or did I miss something obvious?
Thanks for your help
