First, the […]

Arduino LED Exploration

Arduino LED Exploration

My program shows you all of the data on your Led from the first light to the normal operation light. From that data you can pick an RS that is good light, but lower in current. You must build the circuit to run my program. You must open a terminal window when you run my […]

USB Watchdog for Linux with Arduino

USB Watchdog for Linux with Arduino

A watchdog device monitors your computer to see if the OS is still running. If the system has locked up it will reset the system. High end servers come with built in watchdogs, for basic servers and workstations you can pick up a PCI card version for $100+ depending on features. Basic watchdog cards receive […]

Arduino in C: See Your Microcontroller in a New Way

Arduino in C: See Your Microcontroller in a New Way

For this project, you need to have a Linux computer, or else the things I describe will not work. Don’t fret, though, because there are plenty of tutorials out there that will help you. Piecing this together from multiple sources has been hard, but I’ve been able to do it on my Arduino Duemilanove and […]

Circle-A-Sketch

Circle-A-Sketch

This simple project uses an Arduino, a photoresistor, 2 potentiometers, and a resistor and uses basic serial communication between the Arduino and your computer. Basically, the user can draw by controlling two potentiometers (drawing knobs) and the photoresistor determines how dark the circle will be drawn.
