# Amazing Turquoise Carbonite Freezer ## Description 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 ## Project Details - **Owner:** royavanzatti - **Created:** 3/10/2025 - **Last Updated:** 3/10/2025 - **Visibility:** Public ## Key Components ### U2 — [CD4029BPWR](https://www.flux.ai/lcsc/cd4029bpwr.md) - LCSC Part Number: C2862474 - Manufacturer Name: TI(德州仪器) - Manufacturer Part Number: CD4029BPWR - Part Type: Counters / Dividers - Package or Case Code: TSSOP-16_L5.0-W4.4-P0.65-LS6.4-BL **Pins:** - BD [pin 9] - CI [pin 5] - CLK [pin 15] - CO [pin 7] - GND [pin 8] - J1 [pin 4] - J2 [pin 12] - J3 [pin 13] - J4 [pin 3] - PSE [pin 1] - Q1 [pin 6] - Q2 [pin 11] - Q3 [pin 14] - Q4 [pin 2] - UD [pin 10] - VDD [pin 16] ### U3 — [CD4511BE](https://www.flux.ai/jecstronic/cd4511be.md) - License: https://creativecommons.org/licenses/by/4.0/ - Manufacturer Part Number: CD4511BE - Manufacturer Name: Texas Instruments - Part Type: Integrated Circuit - Datasheet URL: https://www.ti.com/lit/ds/symlink/cd4511b.pdf **Pins:** - ~BL [pin 4] - ~LT [pin 3] - A_1 [pin 7] - A_2 [pin 13] - B_1 [pin 1] - B_2 [pin 12] - C_1 [pin 2] - C_2 [pin 11] - D_1 [pin 6] - D_2 [pin 10] - E [pin 9] - F [pin 15] - G [pin 14] - LE/~STROBE [pin 5] - VDD [pin 16] - VSS [pin 8] ### U4 — [CD4017BE](https://www.flux.ai/jharwinbarrozo/cd4017be.md) - Manufacturer Name: Texas Instruments - Manufacturer Part Number: CD4017BE - Part Type: Integrated Circuit - Datasheet URL: https://www.ti.com/general/docs/suppproductinfo.tsp?distId=10&gotoUrl=https%3A%2F%2Fwww.ti.com%2Flit%2Fgpn%2Fcd4017b **Pins:** - 1 / Q5 - 10 / Q4 - 11 / Q9 - 12 / CARRY OUT - 13 / CLOCK INHIBIT - 14 / CLOCK - 15 / RST - 16 / VDD - 2 / Q1 - 3 / Q0 - 4 / Q2 - 5 / Q6 - 6 / Q7 - 7 / Q3 - 8 / VSS - 9 / Q8 *The full schematic, PCB layout, bill of materials, and interactive design are available at [https://www.flux.ai/royavanzatti/amazing-turquoise-carbonite-freezer](https://www.flux.ai/royavanzatti/amazing-turquoise-carbonite-freezer).* --- *Generated from [https://www.flux.ai/royavanzatti/amazing-turquoise-carbonite-freezer](https://www.flux.ai/royavanzatti/amazing-turquoise-carbonite-freezer)*
