Now we can stepped into the light with our favorite microcontroller Arduino! Since a vast number of analog/digital ambient light sensors/light sensor modules are now available at reasonable price, ...

Let me introduce another simple microcontroller-based do-it-yourself circuit that detects motion and excites a light source in a flash. The “snooper” here is an ordinary passive infrared (PIR) motion ...

This project shows how to build a light gauge that uses an LED bar graph to show the measured brightness level. The function “gauge()” is a good example of using “if” statements to analyze sensor ...

As things get smaller, we can fit more processing power into devices like robots to allow them to do more things or interact with their environment in new ways. If not, we can at least build them for ...
