An Arduino Uno-based alarm with motion sensor, three LED outputs and a keypad with password input.

The system has the following features: - PIR motion sensor HC-SR501 to detect movement in the proximity of the device. - LCD display to show alarm state and show input from the keypad. - Membrane switch keypad 4x4 to arm and disarm the system.

ARDUINO PIR Motion Detector With 16X2 LCD: This is a simple project for beginners who have just started using Arduino. This project uses a PIR Motion Sensor and a 16X2 LCD Module to display when the motion was detected and when the motion stopped.

Learn: how to use Arduino with keypad and LCD, how to combine keypad code and lcd code, how to program Arduino step by step. The detail instruction, code, wiring diagram, video tutorial, line-by-line code explanation are provided to help you quickly get started with Arduino.

May 12, 2021 · Today, we’re going to take a step further and create a simple yet fascinating project that combines a PIR motion sensor and a 16X2 LCD module. This project is designed for beginners who are just starting their journey with Arduino.

Mar 10, 2025 · When paired with an Arduino, a motion sensor can be programmed to respond intelligently, creating an efficient and responsive system. This guide explains how motion sensors work, how to connect them to an Arduino, and how to write the code needed to make them function properly.

What does the motion sensor do? Prototype I was designed using an ELEGOO Mega board, LCD, Ultrasonic Sensor, buzzer, and a 4x4 matrix keypad. Fig. 1.1 shows the internal wiring used for prototype I. Most of the digital and communication pins are in use, leaving little room for other components to be added.

Combine the alarm, motion sensor, and LCD code into one file and upload to arduino. The final product will have a motion sensor that when triggered create a buzz noise and display a message on the LCD screen.

Learn: how HC-SR501 motion sensor works, how to connect motion sensor to Arduino, how to code for motion sensor, how to program Arduino step by step. The detail instruction, code, wiring diagram, video tutorial, line-by-line code explanation are …

With a PIR motion sensor integrated with an arduino, we can detect movement and program the arduino to do something once motion is detected. For example, once the motion sensor picks up motion, we can program the arduino to turn on an LED, turn on a motor so that it …
