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 code is an Arduino project for the Digispark Attiny85 to turn on a light source when the PIR sensor detects something ... is routed to P0 of Digispark via a level-inverter transistor C945 (T1). P1 ...

As soon as the light from the laser to the sensor is blocked ... full it already is by displaying the waste level (measured in centimeters) on the Arduino IDE's serial monitor.

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.
