This circuit uses a 4 bit multiplexer (mux) on the left to turn a parallel binary code (whatever you decide to input) into a serial data stream (highlighted) starting at the lsb and moving to the msb. The single serial input is recieved by the demultiplexer (demux) on the right, and converted back into parallel. The value is then stored in memory for one full cycle to allow the entire message to be loaded (if it wasn't stored, you would only get pieces of the message) and finally loaded from memory for display. After this happens memory is cleared to allow it to load new data and the cycle is complete. Wish I had more room to ad an a/d converter. Looking forward to any input or comments. Have fun. -Jolly
