PID? What is it?

Wikipedia says that a proportional–integral–derivative controller (PID controller) is a generic control loop feedback mechanism (controller) widely used in industrial control systems – a PID is the most commonly used feedback controller. A PID controller calculates an "error" value as the difference between a measured process variable and a desired setpoint. The controller attempts to minimize … Continue reading PID? What is it?

ShiftBright RGB LED Module Saves the Day!

I gave up on trying to drive the A6280 directly with the Arduino. macetech.com already did what I wanted but couldn't do myself. They used the A6281 (which doesn't come in a DIP package- only an SMC) on a nice little breakout board with a RGB LED. Yea! So here's the Module.It worked perfectly and … Continue reading ShiftBright RGB LED Module Saves the Day!

Lizard Climate Control Software Operation Description

The goal of the Lizard Climate Control (LCC) software is to control the climate of my lizard's enclosure using the Arduino and other hardware components. It can operate independently of a PC. However it is capable of supplying diagnostic data via the serial port to an attached PC if needed. LCC depends on hardware to … Continue reading Lizard Climate Control Software Operation Description
