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 Bluetooth Appliance Controller Circuit
This project shows how to control a home appliance with Arduino and bluetooth module HC05 sends command from mobile. Then relay switches the AC load like bulb or fan Arduino Bluetooth Appliance Controller Circuit is simple and safe when wired correctly, also it is good for beginners who want home automation. Arduino Code: Code Explanation: […]
Arduino Line Follower Robot Circuit
Arduino Line Follower Robot Circuit uses sensors and motors. IR sensors look at floor all time and they find black line and white area, Arduino read these sensor signals and then it tell motor driver what to do. Motor driver control wheels speed and direction and then robot follow black line by itself. Arduino Code: […]
Simple PIR Motion Detector Circuit
This simple and easy circuit uses a PIR sensor to detect human motion; when motion happens, PIR output goes high and this high signal turns ON an LED through a resistor. Also, this Simple PIR Motion Detector Circuit is easy to make and works with 12V supply. Circuit Working: Parts List: Components Value Quantity Resistors […]
Arduino IR Remote Control RGB LED Circuit
This Arduino project changes RGB LED color with IR remote; press one button and LED changes fast; no touch, no switch, only remote use; IR sensor reads signal and Arduino drives LED and it feels like small smart light; also this Arduino IR Remote Control RGB LED Circuit is easy to build. Arduino Code: Code […]
Arduino LED Dimmer Circuit using IR Remote
This project for Arduino LED Dimmer Circuit using IR Remote make simple LED look like smart light. Here, LED listens to IR remote, IR receiver reads remote signal and then Arduino change LED brightness using PWM. With Arduino and few parts, we can change brightness sitting on sofa and it feel like small home-automation system; […]
