ASCII Table 0-127

ASCII table for characters 0-127.  ASCII stands for American Standard for Code Information Interchange.  Many PC computers and many microcontrollers, including the BASIC Stamp, Propeller, and Ardunio, use this code to assign a number to a keyboard function.  Some numbers correspond to keyboard actions, such as cursor up, cursor down, space, or delete. Other numbers correspond to printed characters and symbols. 

The numbers 32–126 correspond to characters and symbols that can be displayed in the BASIC Stamp Debug Terminal, the Parallax Serial Terminal for the Propeller, the Arduino Serial Monitor, and the Parallax Serial LCDs.  This is also a handy reference for sending text strings between wireless devices.  Some devices may have different responses to code numbers 0–31, and may also make custom use of characters 128–255 (not shown).
