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 […]
Arduino Based Pulse Monitoring Circuit
This project show how to make a simple Arduino Based Pulse Monitoring Circuit. It uses Arduino Nano, pulse sensor, OLED display, buzzer, an LED. The system reads heartbeat from finger sensor. Then Arduino calculate pulse per minute. OLED show result. LED and buzzer give alert when pulse go high or low. Circuit is simple and […]
IR Sensor Based Stick for Blind Circuit
This circuit turns a normal stick into a smart safety tool for blind users. It helps blind person know if any object is near. It uses IR sensor, transistor, buzzer and a 5V regulator IC. IR sensor sees what human eyes cannot. This IR Sensor Based Stick for Blind Circuit is with low cost and […]
DIY Arduino Based Weather Station Circuit
