The GPIO pins on the raspberry pi provide an interface to other hardware devices. Unlike the normal computer interfaces such as USB, Ethernet, or power, these pins can read and write hardware.
We will explore how to use the interfaces and then experiment with a couple of devices.
Finally we will explore a few other things you can do with a Raspberry Pi.
Lets watch a Youtube video about this.
Now that we have seen a demonstration, lets use another tutorial to do it outselves.
Or for another method have a look at: Raspberry gPIo
Lets watch a Youtube video first to see how to configure and run a digital temperature sensor.
Or you might have a look at Adafruit’s Raspberry Pi Lesson 11. DS18B20 Temperature Sensing
