Basic Principles of Arduino Serial Communication Communication Methods and Implementation Serial communication is a method of transmitting data in a bit-wise order. In Arduino, serial communication is mainly achieved through UART (Universal Asynchronous Receiver-Transmitter). UART utilizes two pins, TX (transmit) and RX (receive), to complete the data sending and receiving tasks. Data is transmitted in … Read more
