Since the previous post, I've made a slight change to the circuit I use, and written code for getting the DAC to generate various wavefo...

I've been thinking of building a signal generator based on an Arduino and a DAC. As an experiment, I got hold of a MCP4921 12-bit SPI in...

Many of the interesting ICs you can get only come in surface mount packages like SOIC or TSSOP. For example, I was looking at this interesti...

A few months back, when I was starting to get interested in building electronic circuits again, I thought it would be useful to have an osci...

Adafruit sells a four digit, seven segment LED display . Unlike many of their products, they don't give a lot of help in hooking it up. ...

The Arduino Sensorium that I described in previous posts is limited by the amount of RAM on the Arduino. Recall that it stores readings from...

The circuit design for the Arduino sensorium from a couple of days ago is trivial, so that just leaves the physical construction. There aren...
