Upon startup, the LCD will display a welcome message. IR sensors detect incoming and outgoing cars: IR Sensor 1 manages incoming cars. IR Sensor 2 manages outgoing cars. The system dynamically updates ...

This project focuses on creating an automatic hand sanitizer dispenser using IoT, Arduino, an IR sensor, and a servo motor. The system is designed to provide a contactless and efficient solution for ...

Arduino Code for Speed Sensor In general, the following code makes Arduino to measure the speed of the moving object using two IR sensors and display the object speed in the I2C 16x2 LCD display. When ...

After some searching, I ended up using a microcontroller and a piece of code borrowed from the web that I tweaked and adapted. The microcontroller-based concept was chosen because I wanted to scale ...

In this review of the Maker Uno RP2040 board with the Arduino IDE we could blink LEDs, control RGB LED lights, press the user button to turn on one LED or make the buzzer output some melody, control a ...

This research aims to develop a RADAR system using an ultrasonic sensor (HC-SR04), servo motor (SG90), and Arduino UNO. This RADAR system can detect objects in the vicinity and display information ...
