IC-4017 decade counter

1 Hz Timebase by IC 4017

I used input frequency 10Hz to output 1Hz.This is a 10 divider circuit. When we need a standard digital clock 1 Hz. but we have the input signal is square wave form 10 Hz so need to reduct it lower with digital frequency divider circuit 10 times I suggest that IC 4017 (Decade Counter / […]

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 […]

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. […]

Coin toss electronics using IC NE555-CD4017

This is a review of electronic sound or a violent coin toss. With electronic circuits. This circuit uses integrated digital IC NE555 and CD4017 with LED display easily. Principle of the circuit, when voltage is 5 volts to the circuit C1 will charge through the VR1 and R1 fully. IC1, R2, R3 and C2 to […]

7 Led light running adjust speed by 4017 and 555

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. […]
