sorry for this newbie question, but I am not sure where to go exactly.
I received some sensor components, and the easiest to get started is a temperature sensor. But the sensor has 3 pins, while the AD converter of Arduino Uno has 7 pins. How would I wire up the sensor to read some value on the host laptop?
In general, for other sensors, what are the important mappings to connect a multi-pin sensor to the Arduino board.
Thanks for some guidance!
