Railway Track Accident Prevention Circuit using Arduino
Railway accidents happen because obstacles come on railway track. Many trains cannot stop fast. This project uses Arduino Uno, ultrasonic sensor, relay and motor or servo to give warning or stop mechanism. The system checks distance. If object comes close, relay activates and motor moves barrier or alarm system. This helps to avoid accidents in […]
