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 ...

I have already made some devices using SeeedStudio’s Seeeduino Nano microcontroller boards and Grove Sensors. In this post I am going to show you how to make a simple sound activated electronic switch ...

Arduino, the open-source hardware, software and content platform, has collaborated with Chinese DIY electronics company, Seeed to create the Arduino Sensor Kit. The kit brings Seeed’s Grove sensors to ...

To capture an instant on film or sensor with a camera, you usually need a fast shutter. But alternately a flash can be triggered with the scene in the dark and the shutter wide open. It’s this latter ...

Capacitive sensing isn't limited to your smartphone. In fact, you can use contact with human skin (or any other conductive surface) to trigger almost any circuit. And the Touch Board from Bare ...
