Darkroom Timer
April 99 Stan Ockers (ockers@anl.gov)
Modified by Vassilis Papanikolaou, April 05
Counts down 0-99 min and 0-59 sec giving an alarm at 0
initial counts are held in data EEPROM setable with one button
RBO-RB3 to bases of transistors connect to common cathode of displays.
RA0-RA3 to 1,2,4,8 BCD inputs of CD4511 7 segment latch and driver.
RB7 to start pushbutton used to start countdown and silence alarm.
RB6 goes to time set pushbutton use to sucessively set the digits.
RA4 with pull-up resistor goes to PB to 15 starting counts
RB4 goes to Dot Points
RB5 goes to Relay-Darkroom Timer
