Most Arduino boards have an ADC chip with a 10-bit resolution that can output values from 0 to 1023. Popular boards like the Arduino Uno, Nano, Micro, and Mega are great examples of this.

By leveraging the capabilities of Arduino Cloud, users can unlock the full potential of their Raspberry Pi projects, allowing seamless data visualization and efficient device management.

Arduino checks moisture and sends readings to the Pi. A Python script on the Pi decides when to open the valve. Use systemd to run the monitoring script as a background service. Enhancements: Include ...

This means that while Raspberry Pi can function as a fully-fledged mini-computer capable of running multiple apps at once, while Arduino can only handle limited input and output controls.
