8 bit binary decode

This post is to help answer a question by Phil Savard on the Littlebird Electronics forum.

This simple Max/MSP encapsulated patch decodes an eight bit value (an integer between 0 and 255) and shows separate bit states for all eight bits. This would be useful, for example, to decode the states of eight separate buttons from an Arduino connected to a 4021 parallel to serial IC (see here for example). Two 4021 ICs could be connected to the one Arduino in order to read from sixteen separate buttons.
