6 ‘s application circuits usually 74LS48 , 74LS192 , 74LS00 , 74LS175 , 74LS20 , 74LS02 TTL integrated and used in all the main logic integrated timing Lm555 same

1 and 5 Lm555 circuits are made ​​with square wave oscillator circuit .

1 in the frequency of the circuit is greater than the frequency of the circuit 5 .

Phase 1 Phase 2 5.devr 6 oscillator circuit running circuit are providing

Phase 2 is used in D-type fli – flop integrated 74ls175 is endtegre . There are four units in flip-flops . D FF is a bit memory element . When the clock input to the output that transmits the information . Integrated and which is triggered on the rising edge of 74ls175 button when pressed about the clock output (Q ) is made ​​low . Pressing any button on the doors of the clock signal circuit design is made to be cut .

Phase 3 of the information received 2 deactivate LEDs and 7-segment display is designed to be shown on . namely 2nd half as well which button pressed Phase 3 o the button corresponding LEDs on the burning 8to3 encoder IC ( 74ls148 ) come with 4 btlik information encoded after the NOT gate with terslenip 3to7 decoder IC ( 74ls48 ) and 3 -bit data code of soluble and in the display of a corresponding button number is seen .

By triggering the 5.devre received from 6.devr clockpals makes the process of counting 0-10 . 4 bits for this job up / down ( up / down) counter IC ( 74ls192 ) was used. Integrated ‘s up to each clock integrated in the applied input is counted up . and the door using two integrated circuits were asked to count to 10 .

U12 : B door integrated into the counting of the different outputs can be connected between 0-19 . integrate each 0-9 counts. Information received from the output with integrated decoder still 74ls48 7-segment display using the method demonstrated value is counted in the number .

2 to 4 and 6 of the circuit from any of circuits SINTAL designed to be activated when the buzzer . Hehang a button that when pressed or counter to count to 10 when the buzzer starts crowing .

This fact quiz complicated circuit is the same as used in the logic circuit .
of each competitor before you press the button if buttons are on the front which contestant lamp ( LED ) lights , buzzer, and the system locks itself by playing other boutiques makes passive ..
