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, […]
Touchless Dustbin Circuit using Arduino Uno and Ultrasonic Sensor
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 […]
Ultrasonic Blind Stick Circuit using Arduino
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 […]
Arduino Based Power Inverter Circuit
Inverter is a useful device in electronics. It changes DC (Direct Current) to AC (Alternating Current). In this project for Arduino Based Power Inverter Circuit we will make simple inverter using Arduino. It takes 12V DC and gives 230V AC. We have used Arduino UNO, IC 7809, some transistors and a reverse transformer to get […]
Simple Flame Sensor Circuit using Arduino
Flame sensor is very important for many uses like industry machines, safety check and fire alarm. In this post for Simple Flame Sensor Circuit using Arduino shows how to connect flame sensor to Arduino to find fire. This project is cheap and works well for real-life fire detection. Coding: Code for Flame Sensor Digital (D0) […]
