Deploy the Arduino code: Upload the Arduino code to the target device. We use PlatformIO to upload the code to the Arduino. Use STM as a high-resolution timer: Connect the STM32L476RG to the target ...

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 ...
