Summary of ASCII Table using Arduino
The article demonstrates generating an ASCII table using an Arduino by printing characters with their ASCII values in decimal, hexadecimal, octal, and binary formats through advanced serial printing functions. The project requires no external hardware except an Arduino connected to a computer. The code initializes the serial communication, then iterates through ASCII characters starting from 33 ('!'), printing each character’s representation in multiple formats.
Parts used in the ASCII Table Project:
- Arduino Board
- Computer (for serial communication)
Demonstrates the advanced serial printing functions by generating a table of characters and their ASCII values in decimal, hexadecimal, octal, and binary. For more on ASCII, see asciitable.com
Circuit

None, but the Arduino has to be connected to the computer.
Code
/*
ASCII table
Prints out byte values in all possible formats:
* as raw binary values
* as ASCII-encoded decimal, hex, octal, and binary values
For more on ASCII, see http://www.asciitable.com and http://en.wikipedia.org/wiki/ASCII
The circuit: No external hardware needed.
