Gray code

Gray code, also known as reflected binary code, is a binary numeral system where two successive values differ in only one bit. This property is particularly useful in various applications, such as error correction, digital communication, and position encoding in robotics and rotary encoders. ### Key Features of Gray Code: 1. **Single Bit Change**: As mentioned, in Gray code, moving from one numeric value to the next changes only one bit. This minimizes the chance of errors during transitions.
