First, I’ll quickly explain what is Serial communication. Then you’ll see how to setup your hardware and software, and we’ll dive into the Python code (Cpp for Arduino). A basic example at first, leading to a more complete application using a Raspberry Pi, an Arduino, and other elec...

It is the input voltage supplied to the board which ranges from 7V to 20V. The voltage provided by the power jack can be accessed through this pin. However, the output voltage through this pin to the board will be automatically set up to 5V. Serial Communication串口通信,有4个串口 RXD an...
An Arduino Uno has a single hardware serial port, but serial communication is also possible using software libraries to emulate additional ports (communication channels) to provide connectivity to more than one device. Software serial requires a lot of help from the Arduino controller to send and ...

The Arduino Nano ESP32 (with and without headers) is a Nano form factor board based on the ESP32-S3 (embedded in the NORA-W106-10B from u-blox®). This is the first Arduino board to be based fully on an ESP32,and features Wi-Fi®, Bluetooth® LE, debugging via native USB...
