Code in the Arduino sketch is then used to compute the actual voltage being measured. The analog sensor on the Arduino board senses the voltage on the analog pin and converts it into a digital format ...

Arduino Uno can measure voltages through its analog ... However, your microcontroller, sensor module, operating voltage and high-voltage input might be different. So, you will need to refine your code ...

When something passes in front of a PIR sensor it detects the change in background temperature and then triggers an output voltage. This voltage can be read by an Arduino digital input and then ...

This project is a great example. [Scott Daniels] takes a look at the other voltage measurement options available to AVR chips used by Arduino. If you’ve used the analogRead() function then you ...

[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.
