Love test game circuit by 8 LED

This circuit uses the nand gate IC number is 4011B per Clock signal generator circuit, feeding it with the pin number 14 of the IC counter circuit 4017B.When you press and hold the switch S1 C1 will discharge. Causing current flow through D1 as a result, IC1 work.Clock generator and input to IC2. IC2, which will make the incoming signal. Then display the output from the Q0-Q7 step on the moon, run to the speed of the clock entered.When the switch S1 will IC1 stop source clock input to pin 14 of IC2, the IC2 of the clock will not count. As a result, the output is displayed on a LED lamp or lamps.We can use this circuit as a circuit game in love, by assigning to each LED on the moon has a different meaning with the author as if never hug, love much, etc. Let’s be friends.

4017 Led Pattern-Flasher

The circuit uses a 555 timer oscillator to supply clock pulses of a variable frequency to the 4017 decade counter. The decade counter only needs to have three outputs so the fourth output goes into the reset pin to start the cycle all over again. The central red led is always on. Each row of four leds flash in sequence giving the impression that the light is rotating. It is an idea that works very well giving an eye-catching display. It will run continuously for three hours with a standard pp3 battery.
