Arduino’s real-time alerts for IoT projects offer a powerful tool for enhancing the efficiency and effectiveness of IoT devices.

This enables the Arduino to report the time to the VIC-20 via its IEC port. The project is a neat way to provide a real-time clock source to programs written in Commodore BASIC.

There’s also a DS3231 real time clock to help it keep accurate time. Incidentally, it’s a hefty thing to print, according to YouTuber [Lukas Deem] who replicated the project.
