Sound is everywhere and sometimes we want to know from which side sound comes, example in robot or in security; so with Arduino and some sound sensor we can find sound direction. In this circuit we used four sound sensors and one OLED display with Arduino and OLED show which side sound comes; also this […]

Dancing Water Fountain Circuit with Arduino
The Dancing Water Fountain Circuit with Arduino is a small project that makes water move like a dance when music plays. Sound sensor listen music beat and Arduino controls the motor pump and then pump push water up and down in rhythm of sound. Also, with some LED light, it look very beautiful like mini […]
Arduino Based Obstacle Avoidance Robot Circuit
This project is for making a small robot car and this robot can move and avoid obstacle on road; also it uses Arduino Uno, ultrasonic sensor HC-SR04, motor driver L293D and two DC motors. Furthermore, this Arduino Based Obstacle Avoidance Robot Circuit is simple and good for beginners and then robot check distance with ultrasonic […]
Arduino Based Automatic Gate Opening and Closing Circuit
This project is for Arduino Based Automatic Gate Opening and Closing Circuit and 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 and then Arduino control motor to […]
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. Hence, using this idea we can create letters or shapes with some LEDs and Arduino controls LEDs in speed to make effect of display. This project uses […]
Touchless Dustbin Circuit using Arduino Uno and Ultrasonic Sensor
This Touchless Dustbin Circuit using an Arduino Uno and Ultrasonic Sensor is a simple and useful mini project; people also call it a smart dustbin or an automatic dustbin because it opens and closes automatically without touch. In normal dustbin we have to touch lid by hand which is not hygienic, but in smart dustbin […]
