The Analog Shield was created in collaboration with Stanford University and the TI University Program and is produced by Digilent Inc. It was created to be part of the open source neighborhood and reference materials, demonstration code for the Arduino Uno, files and schematics are consisted of in the collection of Instructables tutorials you can download below.
The origins of the Analog Shield begin with Dr. Gregory Kovacs, teacher at Stanford University who wished to profit from the successes his students were having with the Arduino and use that as a bridge into the world of analog electronic devices. Partnering with the TI University program, his student Expense Esposito worked with TI engineers to produce a shield board that could convert an Arduino board into an effective combined signal prototyping system. Prof. Kovacs has utilized this powerful mix to teach his students essential ideas such as:. Quantization and sampling. Direct digital synthesis. Analog sound vs Digital sound. ... and more.
The following plug-and-play demonstration examples are presently readily available:. FFT Spectrum Visualizer. Direct Digital Synthesis Function generator. Lissajou Pattern Generator. Polyphonic MIDI Gamer.
The Analog Shield is created with TI analog innovation that offers approximately 4 channels of 16-bit analog signal input and output. Likewise on board are incorporated fixed +/ -5 V and variable +/- 7.5 V power materials.
Consisted of is a small 170 point solderless breadboard that can be affixed to the guard itself for prototyping with through-hole components. The guard was created and optimized to deal with the Arduino Uno *.
