The Drum’s Ad of the Day highlights work that stands head and shoulders above the rest. Today’s winner is ‘Stay In The Game’ by Grey London for Pringles.

I made this Arduino 8 bit binary led counter as a solution for one member from Arduino forum. He asked if somebody can make a project that displays a decimal number in 8 bit binary format using 8 leds ...

And now you have your 10-bit Gray-code using consecutive addresses of 0000-to-1001 (0 to 9 in decimal). In this case, the sequence followed by this Gray code counter implementation is: 4, 6, 2, 0, 8, ...

Grey coding ensures that just one bit changes at a time. The example he uses to show the importance of this is when binary code transitions from 7 (0b0111) to 8 (0b1000).
