Red Blue Dual Color Flashing Lights DIY Kit

Red Blue Double Color Flashing Lights DIY Kit Electronics students and hobbyists utilize this classic DIY learning kit to master the fundamentals of timer circuits and sequential logic counters. Consequently, it combines an NE555 multivibrator with a CD4017 decade counter to drive an alternating array of 32 LEDs in a flashing strobe sequence. Therefore, this interactive kit serves as an excellent educational assembly project for practicing soldering skills and understanding clock pulse propagation.

Key Features:

• Dual-IC Architecture: Employs the industry-standard NE555 timer and CD4017 decimal counter for robust hardware-driven logic control.
• Interactive Speed Tuning: Features an onboard adjustable potentiometer to fine-tune the pulsing frequency and control the speed of the alternating flashing banks.
• Clear Component Silkscreen: Features a clearly labeled PCB silkscreen layer with distinct component outlines to guide beginners during manual soldering.
• 32-LED Symmetrical Display: Arranges 16 high-brightness red and 16 high-brightness blue LEDs in clear groups for highly visible, eye-catching emergency light simulation effects.
• Low Power Consumption: Operates efficiently on standard low-voltage DC power sources, making it safe for classroom environments and battery operation.

Technical Specifications:

• Operating Voltage: 9 V to 12 V DC.
• Core Integrated Circuits: NE555 (Timer) and CD4017 (Decade Counter).
• LED Count & Color: 16 × 5mm Red LEDs and 16 × 5mm Blue LEDs.
• Circuit Type: Standalone analog/digital logic multivibrator and counter (No programming required).

Mechanical Specifications:

• PCB Shape: Rectangular light-bar layout board optimized for dual-sided symmetrical component grouping.
• PCB Color: High-contrast green mask with clear white component designations.
• Assembly Type: Through-hole technology (THT) for straightforward manual component population.

Dimensions:

• PCB Length: ≈ 92.00 mm.
• PCB Width: ≈ 32.00 mm.
• Total Kit Weight: ≈ 26.00 g (Includes all discrete components and headers).

Pinout and Wiring:

• Power Input Pad (VCC): Connects to the positive terminal of a 9V–12V DC power source or battery pack.
• Ground Input Pad (GND): Connects to the negative/GND supply terminal.
• Trim Potentiometer (R1): Direct adjustments modify the core RC time constant to slow down or speed up the dual-bank cycle.

• NE555 + CD4017 Red Blue Double Color Flashing Lights Assembly and Schematic Guide

Commonly Used in:

• Vocational Labs: Teaching vocational or engineering students fundamental concepts of clock frequencies and digital counting states.
• Soldering Practice Kits: Standard introductory tool for beginners to gain confidence with through-hole components, IC sockets, and discrete passives.
• DIY Board Games: Serving as an electronic substitute for emergency strobe simulations or visual indicator markers in custom-built electronics projects.

Applications:

• Electronic Skill Training: Enhancing practical understanding of charging/discharging RC time constants and decade counter decoding. However, reversing the input power polarity can permanently destroy both the NE555 and CD4017 integrated circuits; therefore, technicians must strictly verify the positive and negative leads before powering up the board.

Equivalent Models:
