An Arduino project implementing a security alarm system featuring PIN code access via a 4x4 keypad, status updates on a 16x2 LCD, motion detection using an HC-SR04 ultrasonic sensor, and ...

Here we make a project about how to connect LCD display to Arduino board and print a specific text. How to install Arduino IDE we discussed in previous post How to read Arduino board. First step is ...

Radio Frequency Identification is widely used in contactless payment cards, National Highway Tollgate systems, and in security passes. By integrating an RFID reader with an Arduino, you will be able ...

The following project demonstrates "A Real-Time Digital Clock" built using Arduino Uno R3, a 16x2 LCD display, and push buttons—no RTC module required. The project uses Arduino’s internal timing and ...

Have you ever wondered how speed guns measure the speed of moving vehicles or how an athlete's sprint speed is recorded? Normally these speed sensors work with radar or laser technology to bounce back ...
