#As you could see in this image the Arduino UNO is connected to the Ultrasonic Sensor as well as Bread Board. #Arduino's Digital pins are connected to the Bread board ...

Now lets see if the hardware is connected right by uploading the code: #include <Adafruit_NeoPixel.h> #define PIN 2 // Here is where the LED is connected to the Arduino UNO #define NUMPIXELS 10 // ...

Motion detection is a common application for intruder alarms, light switches, and other home and industrial automation applications. And there are several ways to do it. We have already used a PIR ...

An infrared sensor is an electronic module that is used to detect the certain physical appearance of its surroundings by either emitting and/or detecting infrared radiation. IR sensors can also sense ...

When you need to quantify the color of an object, you’ve got quite a few options. You can throw a Raspberry Pi camera and OpenCV at the problem and approach it through software, or you can buy an ...

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 ...

Tilt sensors are essential components in security alarm systems today. Standalone tilt sensors sense tilt angle or movement. Tilt sensors can be implemented using mercury and roller ball technology, ...
