I have done necessary connections (TX to RX, RX to TX, common ground etc. When trying to communicate with multiple serial enabled devices, while also sending info back to the main serial window, a few extra RX/TX ports can be a welcomed thing. In this paper we play with three types of serial communication: standard TX-RX, Soft Serial and I2C. Laptop Arduino board USB to serial Arduino microcontroller USB to serial driver Arduino programmer Processing sketch Java program RX TX-OR--OR--OR- TX USB RX chip USB is totally optional for Arduino But it makes things easier Original Arduino boards were RS-232 serial, not USB. RS232 serial communication is one of the oldest communication where data is sent or received one bit at a time.
