I am trying to create a little quiz type game, like the popular show Sale of the Century. Our family would use the device to determine who will be able to answer the question when the TV show asks a question.
Specifications:
1) There are 3 players each with a press button and 2 LED's, Green and Red.
2) The first button pressed illuminates it's GREEN LED, and locks out the other 2 players, illuminating their RED LED's.
3) There is to be a RESET press button to turn off all LED's and make the circuit ready for the next question/round.
I will use CMOS 4000 series ICs.
Main Gate Type - NAND gates
Switching - Active high switch
LED's - Active high LED's
Quad 2 input NAND gates are to be used, CD4011B.
Inverter - HEX buffer Inverter TC4069
The power supply will be a 9 volt battery.
See the attachment for a diagram.
I have 2 Q's.
1) Need some help with resetting the circuit so all the LED's are off before the next round can begin.
2) Is this the right place to stick the inverter?
