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 …

Analog Sensors Reading with Raspberry Pi as Interface The Raspberry Pi has no built in analogue inputs which means it is a bit of a pain to use many of the available sensors. We need a A/D interface easy to configure in the RPi and the MCP3008 is the answer. The MCP3008 is a 10bit …

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 …

mportant: This document goes along with the code at https://github.com/OlivierLD/raspberry-pi4j-samples/. In the sources, refer to ADC The goal here is to read analog data from a Java program running on a Raspberry PI. For this example, we will be using a potentiometer like this one. When the user turns the knob of the potentiometer, its …
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 …
The Raspberry Pi does not have any analog inputs, but that does not mean that you can’t use some types of analog sensors. Using a couple of resistors and a capacitor, you can use a “step response” method to measure resistance. Which is just great if you are using a pot, photoresistor or thermistor. The …

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 …
