Serial Communication of Arduino with Raspberry PI
Can a Raspberry Pi control an Arduino?
A Raspberry Pi may operate an Arduino in a variety of methods, including through a direct hardware connection (e.g. serial ports or custom GPIO connectors) or wirelessly (e.g. WiFi or Bluetooth).
What is serial communication in Raspberry Pi?
The serial port is a low-level communication channel between the Raspberry Pi and another computer. There are two primary applications for it: Connecting to a PC to allow access to the Linux console.
How do I send serial data to my Raspberry Pi?
To receive data, connect the Raspberry Pi board's GPIO 15 (UART0 RXD) pin to the serial device's TxD pin.
To send data, connect the Raspberry Pi board's GPIO 14 (UART0 TXD) pin to the serial device's RxD pin.
