Data Comms tips

📡

Serial communication (UART) sends data bit by bit. Text must first be converted to bytes, then transmitted as binary pulses — this tool shows the bytes.

💡

Arduino and microcontrollers communicate over serial in ASCII. "Hello " = 48 65 6C 6C 6F 0A in hex = 01001000 01100101 ... in binary.

🔢

The newline grouping mode shows each character on its own line — useful for debugging character-by-character data streams.

📋

Copy the binary output in newline mode and paste it into your documentation or debugging notes to record exact byte sequences.
