Nice guide from Pi My LifeUP via raspberry pi pod:

In this tutorial I go through the steps of setting up a Raspberry Pi ADC (Analog to digital converter). As you may already know the Pi doesn’t have any GPIO pins that are analog. This makes connecting analog sensors a little more complex.

There are several solutions to the lack of Analog pins like the one I did in the Raspberry Pi LDR tutorial which involved using a capacitor to measure the resistance of the LDR (Light Dependent Resistor). A better solution to this would be to use what is known as an analog digital converter (MCP3008). This involves a little bit of setting up which I will go into below

Featured Adafruit Product!

Assembled Pi T-Cobbler Plus – GPIO Breakout – for RasPi A+/B+/Pi 2/Pi 3: The Raspberry Pi B+, Pi 2 and Pi 3 have landed on the Maker World like a 40-GPIO pinned, quad-USB ported, credit card sized bomb of DIY joy. And while you can use most of our great Model B accessories by hooking up our downgrade cable, its probably a good time to upgrade your set up and accessorize using all of the Model B+’s, Pi 2’s and Pi 3’s 40 pins.

That’s why we now carry the Assembled Adafruit Pi T-Cobbler Plus – Breakout + Cable for Raspberry Pi B+/Pi 2 / Pi 3. This Cobbler is in a fancy T-shape, which is not as compact, but is a little easier to read the labels. We also have the more compact original Cobbler Plus. (read more)
