How-to: Use analog Inputs for Raspberry Pi using the MCP3008 #piday #raspberrypi @Raspberry_Pi @ The Adafruit Learning System –

Teaching the Raspberry Pi how to read analog inputs is easier than you think! The Pi does not include a hardware analog to digital converter, but a external ADC (such as the MCP3008) can be used along with some bit banged SPI code in python to read external analog devies. Here is a short list of some analog inputs that could be used with this setup.

Read more & this goes great with our MCP3008 – 8-Channel 10-Bit ADC With SPI Interface.


Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.

  1. There is a bit of repeated text on page two.

    Thanks for this tutorial and stocking this part, exactly what I was looking for.

    A suggestion would be to add the info for hardware SPI for those distributions that allow it, it’ll free up some GPIOs.

    Keep up the good work!

  2. @mike – thanks, we’ll take a look at it. We’ll have a hardware SPI distribution/tutorial shortly
