Analog sensor input raspberry pi using a MCP3008: wiring/installing/basic program

So now that we bought the MCP3008 ADC lets get it up and running! Note: This is my first instructables submision so if something is wrong just tell me so and if you like my style leave a comment, also I’m from the Netherlands so my English might not be perfect. In this project we …

Raspberry Pi Analog to Digital Conversion Experiments and Howto

The Raspberry Pi is a great little educational computer, but all models of the Raspberry Pi miss a critical ingredient for electronics experiments – an Analog to Digital converter. I am constantly working on upgrading my lab, and one of my needs is to measure many channels of analog signals, with reasonably high precision. I …

A simple analog proximity sensor with digital interface (for Raspberry Pi) [last update: Feb 7, 2014]

Raspberry Pi has a Broadcom BCM2835 chip, which controls 26 GPIO (general purpose input/output) pins. There are C library or RPi.GPIO python package available online that can be used to control the pins. The RPi.GPIO package is by default included in most Raspberry Pi system, such as Raspbian, a RPi version of Debian linux system. One …

ADC Circuit: Raspberry Pi Analog Input Circuit on Breadboard

This project shows how to construct a simple MCP3002 Analog-to-Digital Converter (ADC) circuit with a test potentiometer input. It shows how to wire the SPI pins for successful data communication between the ADC and the Raspberry Pi. Breadboard Build A breadboard, or “solderless breadboard”, is a tool, which allows engineers to rapidly prototype their circuit …
