What is Arduino Software Serial

George Bantique April 3, 2020 No Comments

I feel obligated to post this tutorial after seeing beginners assigning two serial devices to Arduino Uno hardware serial pin which is digital pin 0 (Rx) and digital pin 1 (Tx).  Connecting two serial devices results to undefined behavior due to conflicting signals. Arduino Uno, Arduino Nano, and Arduino Mini has only 1 serial port. […]
