U4 74HC154 Col Driver. Pin 19 goes to ATMega. Pin 18 to GND. Pulling Pin 18
HIGH will disable all Col (LEDs). We can add a jumper on this pin in
ClockTHREE. Three way header - centre pin goes to 19 on U4. Left and Right to
GND and +5V.

I think we need an on/off switch for the end user. Direct power supply cutoff
switch.
