Railway Track Accident Prevention Circuit using Arduino
Railway accidents happen because obstacles come on railway track, because many trains cannot stop fast; therefore, this project uses Arduino Uno, ultrasonic sensor, relay and motor or servo to give warning or stop mechanism. The system checks distance and if object comes close, relay activates and motor moves barrier or alarm system, also this helps […]
Arduino Based Pulse Monitoring Circuit
This project show how to make a simple Arduino Based Pulse Monitoring Circuit, as it uses Arduino Nano, pulse sensor, OLED display, buzzer, an LED; also the system reads heartbeat from finger sensor. Then Arduino calculate pulse per minute and OLED show result; after that LED and buzzer give alert when pulse go high or […]
IR Sensor Based Stick for Blind Circuit
This circuit turns a normal stick into a smart safety tool for blind users, as it helps blind person know if any object is near. Also, it uses an IR sensor, a transistor, a buzzer and a 5V regulator IC, here, the IR sensor detects objects that human eyes cannot see. Furthermore, this IR Sensor […]
