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 ...

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 ...

The Pressure Sensor Module incorporates a material called Velostat with the Arduino. This material adds more resistance when more pressure is applied to the material. This module also uses the RGB LED ...

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 ...

Instructables member Patrick Panikulam has created a versatile wireless Arduino pen plotter and laser engraver, powered by an Arduino UNO microcontroller and offering a work area of 200 x 162 mm and ...
