🚗 Driver Drowsiness and Alcohol Detection System Using Arduino & GSM Module Published on: April 18, 2025 Author: Dinesh | Learn with D Trend Introduction Road safety is a paramount concern in today's fast-paced world. Accidents resulting from driver fatigue and alcohol consumption are alarmingly common. To address this issue, I've developed a Driver Drowsiness and Alcohol Detection System using Arduino and a GSM module. This project aims to enhance vehicular safety by monitoring the driver's alertness and sobriety, providing real-time alerts, and taking preventive actions when necessary. Objectives Monitor Driver Alertness: Detect prolonged eye closure indicating drowsiness. Detect Alcohol Consumption: Identify the presence of alcohol in the driver's breath. Automated Alerts: Send SMS notifications to a predefined contact upon detection. Preventive Measures: Disable the vehicle's motor to prevent potential accidents. Components Requ...

YouTube Video for this RC car Introduction In today's world, electronic waste (e-waste) is increasing rapidly, but instead of letting it go to waste, why not  repurpose and rebuild  something amazing? In this project, I took an  old, non-working RC car  from an  e-waste shop  and restored it completely from scratch. My goal was to convert it into a  Bluetooth-controlled RC car  using  Arduino, a Bluetooth module, a 4-channel relay, and a battery . In this blog, I'll  walk you through the entire process —from sourcing the  RC car chassis  to rewiring and coding it for smooth operation. Let’s get started! Materials Required Here are the components I used to restore and upgrade my RC car: ✅ Old RC Car Chassis – Taken from an e-waste shop ✅ Arduino Uno/Nano – Acts as the brain of the RC car ✅ HC-05 Bluetooth Module – For wireless control via a smartphone ✅ 4-Channel Relay Module – To control the motors ✅ 12V Battery (Lithium-io...

        How to create an RFID tag that Activates the motor ...........................................................................Diagram..................................................................             .................................................................Connection route................................................................ How it Works: Setup: Replace authorizedUID with the UID of your authorized RFID tag. The relay module is connected to RELAY_PIN (pin 8). Motor Control: When the authorized tag is scanned, the motor toggles ON/OFF. UID Detection: The program reads the RFID tag's UID and compares it with authorizedUID . Wiring: RFID Reader: VCC → 3.3V RST → Pin 9 GND → GND MISO → Pin 12 MOSI → Pin 11 SCK → Pin 13 SDA → Pin 10 Relay Module: VCC → 5V GND → GND IN → Pin 8  ...................................................................
