Recent research in raspberry pie, exposed to the GPIO pin
Such as I want to get the sensor DS19B20 information
What should I of these pins connect?

I know the VCC is to from the actuators to a power supply, then is 3.3 v or 5 v can receive or regulations can only receive 3.3 or 5?
GND and I know that is in the tree blackberry pie on the GND pin
I know this DQ is used for data transmission, so it should pick up on which foot? Is fixed must connect on the feet or there are other same function of the pin can also meet?
Read online tutorials are just directly tell how should pick up, but the specific why didn't say that, after this encounter other not DQ or don't understand ah.. So I want to consult the bosses!!!!! Thank you for your attention!
