This project was for an engineering design class at the University of Houston Clear lake. There were also two other people working on this project along side myself. All parts were bought on Amazon.

#define LED_PIN 13 // storing pin number 13 inside LED_PIN variable so we can easily identify that we are storing led inside our variable. #define MOTION_SENSOR_PIN 2 // storing pin number 2 inside ...

Automating household or office systems can be achieved using an Arduino Nano, a passive infrared (PIR) motion sensor, and a relay. The primary aim is to create a control system that activates or ...

The PIR motion sensor consists of 3 pins-VCC, GND, and the Data Output Pin. VCC is the power pin of the module. Out is the data Output pin of the module.it goes high when motion is detected. GND is ...

Proximity sensing is a common application for intruder alarms, light switches, and other home and industrial automation applications. There are multiple methods of proximity detection used in the ...
