4017 decade counter 1 Articles Flashy Paper Christmas Tree Does It With A 555 December 13, 2024 by Kristina Panos 11 Comments ...

VCC on a 4017 is 3-15V - It should be perfectly happy at 12V. I'm not entirely sure why he has output 5 tied to reset on the arse end of an op-amp.

Project Overview This project demonstrates the design and implementation of an LED roulette circuit using the 555 Timer IC and 4017 Decade Counter IC. The circuit mimics the spinning effect of a ...

OBJECTIVE The aim of this project is to design and implement an LED roulette circuit that demonstrates sequential LED flashing, controlled using a 555 timer IC in a stable mode and a 4017-decade ...

The circuit consists of a 555 astable oscillator that is used to send clock pulses to the clock terminal of a 4017 decade counter which in turn produces a sequence of pulses. Each progression of pulse ...

A decade counter converts the pulses into 8 pulses (a wiring change makes it reset on the 9th count). The rest of the circuit is nothing more than LEDs, resistors, and diodes.
