This is an Arduino-based Proximity Sensor circuit wired using the popular HC-SR04 Ultrasonic ranging module,used here for non-contact object detection purpose. The HC-SR04 module includes ultrasonic ...

This module provides an introduction to utilizing a gas sensor with the Arduino. It also demonstrates some warning systems that can be implemented with the sensor. Finally, it provides a sensor ...

This morning, littleBits is introducing an Arduino module into the mix. It’ll snap right into place — no soldering required — just like the other littleBits modules, with one big difference ...

He suspected EMF interference so as a quick first step he decided to throw together an EMF detector using an Arduino. It uses a bank of LEDs as an indicator bar to reflect the EMF picked up by the ...

LittleBits is aware of just how intimidating these make-it-yourself gadgets can be, so it has just launched its first software-programmable module, the Arduino at Heart.
