Serial – The basics

The Serial is the default communication protocol of Arduino. This means its via Serial that data transmits. For example, when you upload your code to your Arduino, it is via Serial (with a USB cable). You can check data transmission in real-time with TX and RX LEDs. TX blinking => Arduino is transmitting data. RX blinking => Arduino is receiving data. You can try to upload your code to the Arduino and watch for the RX led
