How to: Bread Board Arduino…
Having a couple of Bread Board Arduinos handy can really make prototyping quick and painless. And while the Bread Board Arduino has pretty much been flogged to death in every...
LocoMotion: MMA8453 with Interrupts…
In the previous post about the MMA8453_N0m1 library we talked about how to get the stream of raw XYZ data back from the accelerometer. In this post we will be...
How to: Compiling the Arduino Bootloader…
A project we’ve been recently working on requires a custom Arduino boot loader. Working in an incremental fashion, the first step is getting the stock Arduino boot loader to compile...
6DOF Arduino: Compass & Accelerometer
This Arduino library is a mixed bag containing a number of functions to facilitate rapid sensor integration between a three axis compass and a three axis accelerometer. Where speed is...
How to: LED as a Light Sensor
LEDs LEDs LEDs, is there anything they can’t do? Besides adding that special crunchiness to smooth peanut butter, they also make awesome light level sensors. Here’s one way to do...
ADC Battery Voltage: Divide, Match and Measure…
While the stock Arduino isn’t particularly well geared to running from a battery source, there are times it will be useful to know the status of our battery voltage. Using...
ColorBabel: Hue to RGB, do you copy?
When talking in the color space one should speak lightly. Illustrated here is a translation from 10 bit hue to discrete 8 bit PWM levels for red, green and blue...
DC Servo: In a State of Motion…
Software and hardware development have converged into a practical test platform. The encoder processing loop has been converted to fast inline assembly and released under GPL. And in the following...
