9-DoF AHRS Sensor Board and RGB LED Matrix Demo

RGB Matrix

 

In this (experimental) episode Shahriar demonstrates two embedded-electronic circuits available for purchase from Sparkfun Electronics. The demos illustrate some of the capabilities of these circuits along with a short instruction on how to interface and operate them. All the code for the AHRS demo and the RGB Matrix demo are available to download.

The first demo is of a 9-degree of freedom (9-DoF) sensor board equipped with three dimension of linear acceleration (accelerometer), angular acceleration (gyroscope) and magnetometer. Using the combined information from these sensors an Attitude and Heading Reference System (AHRS) data can be extracted. The demo shows this system in action using customized Matlab functions. 

The second demo demonstrates the ease of use of an RGB LED Matrix equipped with an SPI interface. A sample C code written for a Microchip PIC18F2455 is used to draw some simple animations.

This is an experimental episode to judge the level of interest in these type of demo videos. Please leave feedback!
