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 […]
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. Also, it use electromagnet and hall sensor; then this hall sensor see magnet position and transistor gives current to coil; furthermore, this make balance of magnet force and gravity, so magnet […]
