How to Connect 100 LEDs using NE555 and 4017 Decade Counter ICs #electronics #ic555

In this tutorial, learn how to build a flexible LED sequencing circuit using the NE555 timer IC as a clock generator and the 4017 decade counter to manage the light patterns. Discover how to chain multiple 4017 ICs to expand your design and control a larger array of LEDs, while also learning how to adjust the sequence speed by modifying component values like the timing capacitor.
