Function: Comprehensive 12-in-1 DIY electronic starter kit designed for beginners and hobbyists to learn circuit design, coding, and hardware integration using the Arduino UNO R3 platform.

Main Controller: Includes an Arduino UNO R3 (SMD) development board with USB cable — the core microcontroller for all programmable experiments.

Components Included:

• 1 × Breadboard (for solderless prototyping)

• 1 × Jumper wire set (male-to-male connectors)

• 1 × 9V battery connector

• 1 × Set of LEDs (red, green, yellow, and blue)

• 1 × Resistor pack (various values for voltage/current control)

• 1 × Set of push buttons with colored caps

• 2 × Light-dependent resistors (LDRs)

• 1 × Male header strip (for pin extensions)

Compatibility: Fully compatible with Arduino IDE and other microcontrollers like ESP8266 or Raspberry Pi for advanced experimentation.

Applications: Ideal for hands-on learning of programming logic, LED control, sensor interfacing, button input handling, and basic electronic circuits.

Assembly: No soldering required — all parts connect through the breadboard and jumper wires for easy setup, modification, and debugging.

Educational Value: Perfect for students, educators, and beginners exploring embedded systems, automation, and IoT foundations through real hardware.

Design: Compact, modular, and reusable components — enabling dozens of creative and programmable circuit projects from a single kit.
