The microcontroller-based concept was chosen because I wanted to scale the sensor system later to suit other applications. Here is the diagram of my Arduino infrared close proximity sensor. As you can ...

By counting the pulses from the output of the sensor, we can easily calculate the water flow rate (in litre/hour – L/hr) using a suitable conversion formula. The Arduino Sketch (code) uses the ...

[Flux Axiom] is using an Arduino Mega in his setup along with a cornucopia of sensors and all their data is being logged onto an SD card. All the code used in his setup is available in his GitHub ...

What happens when an engineer builds a smart garden? This Arduino-powered system automates watering while collecting ...

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 ...

When something passes in front of a PIR sensor it detects the change in background temperature and then triggers an output voltage. This voltage can be read by an Arduino digital input and then ...

Labeling bottles manually takes a good chunk of time and effort. Addressing this, the YouTube channel Easy Home Made Projects ...

but getting an Arduino starter kit is more convenient. Most already come complete with the UNO board and a bunch of components like LEDs, a temperature sensor, a DC motor, a servo motor ...

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 ...

Most Arduino cameras use the SPI bus for data transfer. Also check out the Seeed Arduino Sensor Kit ($36) available at Kiwi Electronics. One of Arduino's biggest strengths is the ability to attach ...
