The DAT Nefertiti is a comprehensive, all-in-one electronics education and prototyping training board designed for learners across different educational levels—ranging from Grade 6 school projects to high school (Grades 11–12) and university-level engineering.

Key Components and Functional Units on the Board:

• Central Breadboard: A large solderless breadboard featuring marked power rails for building and modifying prototype circuits without soldering.

• Power & Signal Controls: Includes DC supply terminals (ground sockets paired with fixed +3.3V, +5V, +12V, and variable 0 to -12V), a signal generator, a power button, and a buzzer for alarms and alerts.

• Inputs & Controls: An 8-switch array (S1–S8) for manual binary inputs, and two potentiometers (a 100 kΩ and a 10 kΩ rotary control) for adjustable analog input and voltage division.

• Outputs & Displays:

  • An 8-LED array (LED 1 through LED 8) to show digital states and sequences.

  • A rectangular character LCD module.

  • A compact graphical OLED module.

  • A two-digit seven-segment display with segment terminals.

• Switching & Measurement: A relay unit for controlling separate switched circuits, and a dedicated multimeter interface with measurement sockets and lower controls.

• Controller: An Arduino-compatible microcontroller module featuring labeled I/O headers, reset, and programming buttons.
