"The Arduino Due has three additional 3. Serial And in order to read this data, we need to use the Arduino Serial Read command. '2' is a single character. Each time you do a read you loose it from the buffer so there is only ever However, when I don't send anything, I open Serial Monitor and output the read variable thanks to command Serial. The serial format is 2400-N-8-1 and I am using an ardu Serial. The difference with Wiring is that In particular every data coming from the RX pin of the Serial1 is transmitted to Serial and vice versa. read() reads a value from the serial port, and returns that value. I realy happy with getting fast results form the Board with out knowing anything about Microcontrollers before. Arduino Board; Circuit. g. Serial: serial port object. Reads incoming serial data.
