Finally, your Arduino toolkit will be incomplete if you don't purchase some sensor and circuit modules. After all, you can’t build a precise weather station without a BME280, DHT22, DS18B20, or ...

Don't worry, the coding is simple enough to understand even without prior experience. An Arduino is a much better choice than a Raspberry Pi for tasks that require real-time input and responses.

Use Arduino to handle sensor input and relay control. Pi runs a Python Flask server with a simple UI to toggle GPIO pins via serial commands sent to the Arduino. Use cron jobs on Linux to schedule ...
