How to Build a Distance Sensor Danger Alarm System with Arduino Uno, I2C LCD & Buzzer

Distance Sensor Danger Alarm System with Arduino Uno, I2C LCD and Buzzer Hi everyone! Welcome to my video tutorial. This video was created to fulfill the Midterm Exam (UTS) assignment for the English course. Student Information: Name: Wildan Bagus Saputra Student ID (NIM): 253305112 Class: 3D Study Program: D3 Electrical Engineering Institution: State Polytechnic of Madiun Project Overview: In this video, I demonstrate step-by-step how to build a Distance Sensor Danger Alarm System using an HC-SR04 Ultrasonic Sensor, a 16x2 I2C LCD, and a Passive Buzzer powered by an Arduino Uno. Alarm Thresholds: Distance 0 to 5 cm : Status BAHAYA (Rapid Beep / 2500 Hz) Distance 5 to 10 cm : Status WASPADA (Medium Beep / 1800 Hz) Distance 10 to 15 cm : Status SIAGA (Slow Beep / 1000 Hz) Distance above 15 cm : Status AMAN (Silent) Hardware Components: Arduino Uno Board HC-SR04 Ultrasonic Sensor 16x2 LCD with I2C Module (0x27) Passive Buzzer Module Breadboard and Jumper Wires USB Cable Wiring Connection: HC-SR04: VCC to 5V | GND to GND | Trig to Pin 9 | Echo to Pin 10 I2C LCD: VCC to 5V | GND to GND | SDA to Pin A4 | SCL to Pin A5 Buzzer: Signal to Pin 8 | VCC to 5V | GND to GND Thank you for watching!
