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 […]

Arduino Based Obstacle Avoidance Robot Circuit
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 […]
Arduino Based Automatic Gate Opening and Closing Circuit
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 Project with LEDs and Arduino Circuit
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, […]
Electromagnet Levitation Circuit with Hall Effect Sensor
Magnetic levitation is fun science project. In this Electromagnet Levitation Circuit with Hall Effect Sensor, small magnet can float in air without a touch. It use electromagnet and hall sensor. Hall sensor see magnet position and transistor gives current to coil. This make balance of magnet force and gravity, so magnet look magic floating. It […]
Simple DIY Automatic Plant Watering Circuit
Plant need water but many time we forget. For this problem we have made a Simple DIY Automatic Plant Watering Circuit Project use soil sensor, small pump, MOSFET and some parts. System checks soil wet or dry and pump start only when soil is dry. Circuit is very easy with no Arduino and with no […]
