The cycle is routed through a dropping resistor R4 to the basis of the transistor T2. The transistor T1 is controlled with the inverted cycle
via the gate IC1C. If the button is not pushed, no voltage is applied to the light emitting diodes and no LED is lit. If the button is pushed
while the yellow LED is lit, the transistor T2 is passed through and the green LED can light up. Pushing the button while the yellow LED
(V1) is off, the transistor T1 is passed through via the inverter (IC1C) and the red LED can light up. The transistor T2 is locked at this time
and the green LED can light up. Keeping the button pushed will lead to the red and green LED flashing alternatingly.

3.6 Gambling

The rules of gambling are explained quickly. This is about pushing the button at the right moment. It is only rarely possible to make the
LED light up by pushing a button. After the button is pushed, the circuit is passed on to the next gambler, who is allowed to try his luck.
The gambler who manages to light the LED is the lucky winner.

Circuit Description

A slow cycle that briefly switches to a high level every 7-8 seconds is running in the background. If the button is pushed at this time, the
LED can be made to light up.
