This project demonstrates communication between an Arduino master and multiple slave devices using RS485 modules. The master Arduino has buttons to toggle individual pins on the slaves, and each slave ...

Contains examples of Modbus (RS485) communication with Arduino. In the examples, Arduino Mega is used as the Master, and Arduino Uno is used as the Slaves. The Arduino RS485 Module is used for RS485 ...

What You'll Learn: Master UART serial communication, GPS data parsing with TinyGPSPlus library, and location tracking with latitude, longitude, and time data. Applications: Enables GPS-based ...

So here’s the thing: Arduino’s built-in memory is tiny. If you’re just blinking LEDs, no problem. But the moment you try to log data, say battery usage, temperature over time, or GPS coordinates, ...
