Here is the diagram of my Arduino infrared close proximity sensor ... on a potential object in front of the sensor. Using pulsed light enables the sensor to distinguish the reflection from the ambient ...

We know that measuring the speed of light with an Arduino is possible ... the time of the reflection. Because his blinkenlight shield can be used as a light sensor, all that’s needed is a ...

There are loads of unique sensors available on the market for Arduino boards ... to detect movement. Light is emitted and the sensor will trigger if it can't detect its reflection, enabling ...

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 ...

Because of the affordability and seeming ubiquity of the Arduino platform, they have been hard at work this last month trying to get their Geiger counter sensor board for an Arduino out the door.
