Arduino Stack Machine Simulator

A simple Arduino sketch that simulates a stack machine, allowing you to execute stack-based operations via serial communication.

Table of Contents

Introduction

This Arduino sketch provides a basic stack machine simulator, allowing you to push and pop values from a stack and perform arithmetic operations (addition, multiplication, and division) using simple commands. It's designed for educational purposes and can be used as a starting point for learning about stack-based systems and basic arithmetic operations.

Features

  • Push values onto the stack.
  • Pop values from the stack.
  • Perform addition, multiplication, and division operations.
  • Error handling for stack underflow and division by zero.
  • Interaction via the Arduino Serial Monitor.

Requirements

  • Arduino board (e.g., Arduino Uno)
  • Arduino IDE or online IDE (e.g., Tinkercad for simulation)
  • Serial communication tool (e.g., Arduino Serial Monitor, Tinkercad's Serial Monitor)

Usage

  1. Upload the provided Arduino sketch to your Arduino board using the Arduino IDE or compatible online platforms.
  2. Open the Arduino Serial Monitor or use a serial communication tool if you're using Tinkercad.
  3. Enter instructions in the Serial Monitor to interact with the stack machine. Supported commands include:
    • PUSH <value>: Push a floating-point value onto the stack.
    • POP: Pop the top value from the stack.
    • ADD: Perform addition on the top two stack values.
    • MUL: Perform multiplication on the top two stack values.
    • DIV: Perform division on the top two stack values (avoiding division by zero).
  4. Observe the stack's current state and any operation results in the Serial Monitor.

Examples

Here are some example instructions you can enter in the Serial Monitor:

  • PUSH 42: Push the value 42 onto the stack.
  • PUSH 10: Push the value 10 onto the stack.
  • ADD: Perform addition on the top two stack values.
  • MUL: Perform multiplication on the top two stack values.
  • DIV: Perform division on the top two stack values.
