[electron_plumber] made an LED that can be blown out like a candle, and amazingly it requires no added sensors. The project uses an Arduino to ... as a temperature sensor. A diode’s voltage ...

The Pressure Sensor Module incorporates a material called Velostat with the Arduino. This material adds more resistance when more pressure is applied to the material. This module also uses the RGB LED ...

When you need to quantify the color of an object, you’ve got quite a few options. You can throw a Raspberry Pi camera and OpenCV at the problem and approach it through software, or you can buy ...

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 ...

With each contact you make, the red LED lights up ... and B) with only an Arduino UNO, ultrasonic sensor, force-sensitive resistor (or push button), and piezo buzzer. The tone generated depends ...

The example project Arduino Bin Level Sensor presented here incorporates a simpe force sensitive resistor (FSR) for monitoring common bins with solids and some liquids whether conductive or ...
