Pinout/Connection Diagram

cd4040 Circuit

Odds for lottery are set by diode matrix connected to output of 4040 counter. Range is from 1 :2 to 1 : 1024. To use, close scramble switch for a second or two to make free-running oscillator drive counter at high rate, then let contestant hit toueh plate to trigger flip-flop that advances counter one step. If counter was frozen at next to last connected diode, next diode is biased off and Q2 energizes buzzer. For 50-50 odds, connect only diode at output Q1. For odds of 1 in 10, connect diodes only to outputs Q2and Q4 for binary 1010 or 10. With all diodes connected as shown, odds are 1:1024.-J.
