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 ...

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 bu… ...

Here is the diagram of my Arduino infrared close proximity sensor. As you can see, ... [code] #define ALERT_LED 13 //SIGNAL LED . void setup() { TCCR1A = 0b10110010; ... Using pulsed light enables the ...

Now that you've seen how to blink your Arduino's LED, we'll use one final, slightly more complex example: we'll use a third-party UNO breakout board and an external traffic light sensor board to ...

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 ...
