Using pulsed light enables the sensor to distinguish the reflection from the ambient infrared environment. However, do not put it too close to a strong source of infrared radiation because if the ...

This is a simple arduino project for a soil moisture sensor that will light up a LED at a certain moisture level. It uses Arduino Duemilanove microcontroller board. Two wires placed in the soil pot ...

The additional sensors include a nine-axis Inertial Measurement Unit, as well as temperature, pressure, humidity, light, color, and gestures sensors.

An Arduino uses a set of LEDs and an RFID reader to bring the object alive. A matching ring contains the RFID tag that activates the lights when held up to the lantern’s lens.
