TTL Serial Communication Explained | Part 2

The video tutorial explains TTL serial communication, a method used in serial communication protocols. It covers the basics of TTL, how it works with USART transmit and receive pins, and the process of sending messages using start, data, parity, and stop bits. The tutorial also highlights the use of this communication in Arduino projects.

What does TTL stand for in TTL serial communication?

• Transistor Transmission Line

• Transistor Transistor Logic

• Transmission Transmission Line

• Total Transmission Logic

In TTL serial communication, what is the role of the transmit pin?

• To terminate the communication

• To send data to the receiver

• To receive data from the sender

• To check for errors in the data

What is the first step in the serial communication protocol?

• Sending a parity bit

• Sending a stop bit

• Sending a start bit

• Sending a data frame

What is the purpose of a parity bit in serial communication?

• To stop the communication

• To send the actual data

• To check for errors

• To start the communication

Which function is used in Arduino to begin serial communication?

• serialStart

• serialBegin

• serialConnect

• serialInit
