If you've always wanted to try to build an Arduino project, this may be a great way to start. Matt Williamson built a tiny, Arduino-based motion sensor that will SMS you when something moves by ...

Schematic of the ACS712 Current Sensor Circuit (tested circuit diagram of the current sensor module) The internal resistance of this conductive path is 1.2 mΩ typical, providing low power loss. The do ...

Simple Proximity Sensor. 18 Comments . by: Mike Szczys. April 20, 2012. Title: ... He wanted a standalone sensor for his Arduino projects which would use a single pin as a trigger.

The idea is simple enough: just place a INA219 current sensor between the power supply and the microcontroller under observation, and record the resulting measurements as it goes about its business.

Here is an ultra simple Arduino Night Alarm project wired around a handful of inexpensive and easily available components. One advantage of using Arduino as a security system is the flexibility!

Researchers at Yokohama National University have created a liquid-based tilt sensor that only needs simple interface electronics – some 10MΩ resistors and a Microchip ATmega microcontroller in the ...
