This sensor allows us to interact with the external environment, through intensity of light. The photoresistor is based on light resistance, it will sense the light and will allow the microcontroller ...

Because his blinkenlight shield can be used as a light sensor, all that’s needed is a mirror and a pretty long line of sight. There’s a few problems with the setup though: with the Arduino ...

This tutorial will guide you through the process of building a tachometer around an Arduino. Tachometers are ... would have been to use a reflectance sensor which allows to for the transmitter ...

The microcontroller-based concept was chosen because I wanted to scale the sensor system later to suit other applications. Here is the diagram of my Arduino infrared close ... receiver IR1 is only ...

Most ambient lights and sensors are designed to generate light to even out the picture on the front of the panel and reduce any light bleed from the back of an LCD display. This Arduino-powered ...
