Dancing Water Fountain Circuit with Arduino is small project where water moves like dance when music is played. Sound sensor listen music beat and Arduino controls the motor pump. Pump push water up and down in rhythm of sound. With some LED light it look very beautiful like mini musical fountain at home. Circuit is […]

This project is for making a small robot car. Robot can move and avoid obstacle on road. It uses Arduino Uno, ultrasonic sensor HC-SR04, motor driver L293D and two DC motors. This Arduino Based Obstacle Avoidance Robot Circuit is simple and good for beginners. Robot check distance with ultrasonic sensor. If obstacle is near then […]

This project is for Arduino Based Automatic Gate Opening and Closing Circuit. This system uses Arduino UNO, Ultrasonic sensor, NPN transistor, Servo motor, LCD display ,12V battery and few resistors. When someone comes in front of the gate the ultrasonic sensor detect distance and send signal to Arduino. Arduino then control motor to open or […]

POV means Persistence of Vision. Our eyes cannot see very fast blinking light separately. If light blinks very fast then we see it like a line or picture. Using this idea we can create letters or shapes with some LEDs. Arduino controls LEDs in speed to make effect of display. This project uses Arduino Nano, […]

This is simple and useful mini project for Touchless Dustbin Circuit using Arduino Uno and Ultrasonic Sensor. It is called smart dustbin or automatic dustbin. In normal dustbin we have to touch lid by hand which is not hygienic. In smart dustbin the lid opens automatically when person comes near. It uses Arduino, ultrasonic sensor […]

Blind people have big problem on road because they cannot see object in front. To solve this we made an Ultrasonic Blind Stick Circuit using Arduino Stick can sense object and buzzer which make sound to warn blind person. This project is with low cost and easy to build with parts like Arduino Nano, ultrasonic […]
