So how do you know which pins to connect your sensors to? Thankfully, there are several good resources that you can reference while connecting sensors to your Raspberry Pi 3 board. In case you are curious, this is how the GPIO pins looks like on a Raspberry Pi 3 B+:Īlthough there is the word GPIO on the circuit board that indicates what those pins are, there is no indication on what each individual pin does. Undeniably, the GPIO (general-purpose input/output) pins along the top edge of your Raspberry Pi 3 board is what makes it so useful for IOT projects.
