The code is an Arduino project for the Digispark Attiny85 to turn on a light source when the PIR sensor detects something. Note that after powering the PIR sensor module, it needs about 10 to 60 ...

Apart from the Arduino UNO, the circuit consists of two more primal ... light and by detecting its reflection on a potential object in front of the sensor. Using pulsed light enables the sensor to ...

Because his blinkenlight shield can be used as a light sensor, all that’s needed is a mirror and a pretty long line of sight. There’s a few problems with the setup though: with the Arduino ...

Using motion detectors and an Arduino you can trigger lights, fans, or even an pneumatically controlled cleaver-wielding clown to help add your house to the “if you dare” list. There are ...

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 ...

Instead of measuring light, we measure the ambient voltage field on pin A5 and use it to detect if someone is too close to our Arduino. A5 is used as a ... of statistical averaging to reduce noise in ...

[Sebastian Tomczak] was borrowing a homeade muon detector from his friend, and managed to hook it up to his computer through an Arduino. The detector itself uses 3 fluorescent tubes to detect ...

One of the essential parts of any home security system is a door detector that lets you know ... The system here uses a cheap Arduino board, a few sensors, and a magnetic contact switch.
