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 ...
Serial communication is simplya way to transfer data. The data will be sent sequentially, one bit at a time (1 byte = 8 bits), contrary to parallel communication, where many bits are sent at the same time. UART protocol More specifically, when you use Serial with Arduino and Raspberry Pi...
void setup() { // initialize serial communication at 115200 bits per second: Serial.begin(115200); //set the resolution to 12 bits (0-4096) analogReadResolution(12); } void loop() { // read the analog / millivolts value for pin 2: int analogValue = analogRead(1); int analogVolts ...
