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.

I got a couple of INA 219 modules from an online seller overseas. I was looking for a different dc current sensor module to start a small battery charger project, so I welcomed them. The INA219 based ...

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.

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.

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 ...

The Nixie tube, a neon-filled tube with a series of 10 cathodes shaped like numerals, is a classic display for any build wanting a unique, vintage, or steampunk aesthetic. We shouldn’t be surprised a ...
