10 LED roulette with TC4011-LM4017

When entering the power supply circuit, and switch S1 (Start), which is attached press release switch off.Then current is flowing through R1, R2, and C2.
Makes the capacitor C2 caused up When the switch S1 allows the C2 to discharge through R3. The pressure this causes the clock input to the pin 8 of IC1a. The IC1a which will work with production IC1b frequency to send it to the leg 14 (Clock) Of IC2.The IC2 is a driver by ICs LED 10 is illuminated by the moon to the incoming frequency. The IC1d the IC1c and work together. It will serve up audio frequency generator, and then sent to the Piano Society (PZ1) loud beep came out with LED light period.

0-99 counter by IC 4017×2

When you want the counter circuit since 0 arrive at 99. I thinks this circuit may on the same wave length you certainly. it uses IC LM4017 decade counter/divider follow circuit picture. When feed a signal clock at 14 pin cause the position logic at a pin output. From 0 to 99 for switch S1 perform choose RUN or Reset. Please see circuit picture will understand increasingly. Almost forget integrated number this circuit, want the fire feeds 3V low arrive at 15V because be IC digital CMOS there.

Nite Rider Lights

As a keen cyclist I am always looking for ways to be seen at night. I wanted something that was a novelty and would catch the motorists eye. So looking around at my fellow cyclists rear lights, I came up with the idea of ‘NITE-RIDER’. NINE extra bright LED’s running from left to right and right to left continuously. It could be constructed with red LEDs for use on the rear of the bike or white LED’s for an extra eye catcher on the front of the bike.

All IC’s are CMOS devices so that a 9V PP3 battery can be used, and the current drawn is very low so that it will last as long as possible.

The circuit comprises of …

1 555 timer IC4.
1 4027 flip flop IC1.
2 4017 Decade Counter IC2 and IC3.
3 4071 OR gate IC5, IC6 and IC7.
1 470 Ohm resistor 1/4 watt R3.
2 10K resistors 1/4 watt R1 and R2.
1 6.8UF Capasitor 16V C1.
9 Super brght LED’s 1 to 9.
1 9V PP3 Battery.
1 single pole switch SW1.
1 Box.

How The Circuit Works.
IC4, C1, R1 and R2 are used for the clock pulse which is fed to both the counters IC2 and IC3 Pin 14.
IC1 is a Flip Flop and is used as a switch to enable ether IC2 or IC3 at pin 13.
IC7a detects when ether IC2 or IC3 has reached Q9 of the counter pin 11.
IC5, IC6 and IC7a protects the outputs of the counters IC2 and IC3 using OR gates which is then fed to the Anodes of the
LED’s 1 to 9.
