cd4017

The simplest LED running light circuit based on the NE555 timer and CD4017 decade counter

Simple Clap Switch Circuit using CD4017 for clap-controlled relay switching (ECE 6th Semester Minor Project, IIIT Bhopal).

Automatic Light Controller using CD4017, LM358, IR Sensor, and Relay for smart home appliance automation and energy-efficient lighting control.

Design of A Colour Sequence Detector for a 5-core Harness Cable

This is the LED 'J' Sequencer, a project I built for my uncle's birthday! It features 20 LEDs arranged to form the letter 'J', which light up in sequence. The "brains" are a trusty 555 timer and two CD4017 decade counters – no microcontrollers here, just good old-fashioned discrete logic fun. Check out the details to see how it works!

Arduino SS Micro (Leonardo/Pro Micro) keyboard firmware upgrade for a Razer Cynosa Lite, AK5000, or similar single zone RGB keyboard. Easily adapted to any conventional membrane keyboard.

Traffic Light Controller using NE555 Timer and CD4017 (Proteus Simulation) Designed and simulated an automatic traffic light controller in Proteus using the NE555 Timer and CD4017 Decade Counter. Implemented sequential traffic signal control and verified circuit functionality through simulation.

Running Light soldering/3d-printing project for beginners

Hardware-based dual digital dice with 555 timers, CD4017 counters, and seven-segment displays.
