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 ...

This project measures the input voltage using an Arduino Uno and displays it on a 16x2 I2C LCD screen. It uses a simple voltage divider circuit to safely read voltages up to 12V. The Arduino reads an ...

The sensor continuously sends out infrared light and measures how much of that light is reflected. When a reflective object is within its set detection range, it returns a low signal. The Arduino ...
