This project features a two-stage counter and LED blinking system utilizing key electronic components: 555 timer, CD4029, CD4511, a 7-segment display, and CD4017. In the first stage, the system executes a countdown from 3 to 7, with each number changing every 1.5 seconds to ensure precise timing. Once the countdown completes, the second stage is activated, triggering an LED to blink at 1Hz continuously for 5 seconds. This innovative design offers a seamless transition between functionalities, making it ideal for sophisticated digital electronics applications. #TwoStageCounter #LEDBlinking #555Timer #CD4029 #CD4511 #7SegmentDisplay #CD4017 #DigitalElectronics #TechInnovation #ElectronicsDesign
