Introducing the Analog Shield: Designed to bring the world of Analog Electronics to the Arduino™ Uno.*
The Analog Shield was created in collaboration with Stanford University and the TI University Program and is manufactured by Digilent Inc. It was designed to be part of the open source community and reference materials, demo code for the Arduino Uno, files and schematics are included in the collection of Instructables tutorials you can download below.
The origins of the Analog Shield begin with Dr. Gregory Kovacs, professor at Stanford University who wanted to capitalize on the successes his students were having with the Arduino and use that as a bridge into the world of analog electronics. Partnering with the TI University program, his student Bill Esposito worked with TI engineers to create a shield board that could convert an Arduino board into a powerful mixed signal prototyping system. Prof. Kovacs has used this powerful combination to teach his students fundamental concepts such as:
Quantization and sampling
Direct digital synthesis
Analog noise vs Digital noise
The following plug-and-play demo examples are currently available:
FFT Spectrum Visualizer
Direct Digital Synthesis Function generator
Lissajou Pattern Generator
Polyphonic MIDI Player
The Analog Shield is designed with TI analog technology that provides up to 4 channels of 16-bit analog signal input and output. Also on board are integrated fixed +/-5V and variable +/- 7.5V power supplies.
Included is a small 170 point solderless breadboard that can be affixed to the shield itself for prototyping with through-hole components. The shield was designed and optimized to work with the Arduino Uno* - you can purchase your Uno from various retailers across the USA.
* chipKIT Uno32 is hardware and software compatible with the Arduino Uno and is available to purchase through DigilentInc's website. However, examples and code are not currently optimized for the platform.
The Analog Shield library with demos is a combined effort between Digilent, Stanford University and Texas Instruments. The result is an expansion shield paired with a library that works with both Arduino UNO and multiple chipKIT models. With the Analog Shield library, the end user can use simple commands to read from the analog-to-digital converter or write to the digital-to-analog converter.
