If you are designing your own intelligent “Graden Computer” with an optional digital plant moisture sensor/water pump controller that lights an LED to alert the user when it is time to water a potted ...

Arduino enthusiasts and beginners may be interested in a new add-on board designed for the Arduino Uno microcontroller featuring 10 of the most popular modules and sensors for the Arduino platform.

This RCWL-0516 module has the characteristics of high sensitivity, high induction distance, high reliability, large induction angle, wide power supply voltage range, etc. it is widely used in various ...

The title says it all – this article describes a microcontroller-compatible current sensor module you can build yourself, using an inexpensive 8-pin chip as an ‘active shunt’ for measuring ac/dc ...

This project is a simple modification of the LightGauge project. 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.

Last year, my daughter and I had the opportunity to try out Littlebits – magnetic circuits that make it easy for kids to create a variety of simple projects – for a few weeks. She's been talking about ...

WiFi and Bluetooth were never meant to be the radios used by a billion Internet of Things hats, umbrellas, irrigation systems, or any other device that makes a worldwide network of things interesting.

The world of littleBits (the “not-a-toy” toy that I reaaaally wish existed when I was younger) just got a little bit bigger: it can now play friendly with Arduino. If you’re not familiar with ...

In this fun project an ultrasonic distance sensor is used to detect a “target” (i.e., a person, a cat, a burglar, etc.). The Arduino illuminates (blasts) the target using an inexpensive laser diode ...
