The Digital Gated Emulator circuit utilizes a microcontroller to simulate basic logic gates: NOT, OR, and AND. The architecture of the circuit includes a microcontroller unit (MCU), which serves as the central processing unit for interpreting the inputs and controlling the outputs based on the selected logic gate.

The circuit features two Single Pole Double Throw (SPDT) switches that allow for the selection of two input signals, which can be either high (logic 1) or low (logic 0). The state of these inputs is read by the microcontroller, which processes the logic operation based on the selected gate.

A selector switch is incorporated into the design, enabling users to choose which logic gate to emulate. This switch is connected to the microcontroller's input pins, allowing it to determine which gate's logic should be applied to the inputs. The selection of the gate is visually indicated through three dedicated LEDs on the board, each corresponding to one of the gates: NOT, OR, and AND. When a gate is selected, the respective LED illuminates, providing a clear indication of the current operation being performed.

The output of the circuit is represented by a single LED, which signifies the result of the logic operation based on the selected gate and the current input states. The microcontroller executes the logic functions as follows:
- For the NOT gate, the output is the inverse of the input.
- For the OR gate, the output is high if at least one of the inputs is high.
- For the AND gate, the output is high only when both inputs are high.

This setup allows for hands-on experimentation with basic digital logic concepts, making it an educational tool for understanding how these fundamental gates operate within digital electronics. The circuit can be powered by a standard DC power supply suitable for the microcontroller and associated components.This project Digital gated Emulator using Microcontroller is used to emulate the basic gates such us NOT, OR, AND.
