Virtuabotix Buck Regulator Buckboard 5V 3A Voltage Regulator powering an led on a breadboard

Buck Regulator: Virtuabotix Buckboard 1.1 Pinout & Usage Guide

I am happy to announce that with the resounding success of the Virtuabotix Buckboard 1.0, we have upgraded the Buck Regulator board to the Virtuabotix Buckboard 1.1. The board has already found a home in loads of your projects, and I hope that this pin-out guide will help others integrate this awesome Buck Regulator into their own […]

Advanced Arduino Accelerometer Guide: Converting Analog readings to G-Forces +

By popular request our next project is to create a library that handles the MMA7361 3 Axis Accelerometers operation and translate the analog reading into something more “Physics Friendly”. There are several areas of concern when trying to create a library of this kind: First there is the problem of variances from one device to […]

Virtuabotix DS1302 Battery Backed RTC Module for the Arduino and Versalino connected to Arduino Mega

Virtuabotix DS1302 Real Time Clock Module Pin-out and coding guide

The DS1302 trickle-charge timekeeping chip contains a real-time clock/calendar and 31 bytes of static RAM.  It communicates with a microprocessor via a simple serial interface.  The Real Time Clock / Calendar provides Seconds, Minutes, Hours, Day, Date, Month, and Year information.  Only three wires are required to communicate with the Real Time Clock / RAM: […]
