Troubleshooting Your Arduino Base 2 Calculator

Creating a calculator with an Arduino can be an exciting project, but not without challenges. If you're struggling with a base 2 calculator not working correctly in your C+ + code, you're not alone. This guide will help you understand what might be going wrong and how to fix it.

Understanding the Problem

The primary issue here is that the variables nr1 and nr2 are crucial in performing calculations, especially in a base 2 system. In the provided code, the logic to read the inputs for nr2 was omitted, which could lead to incorrect calculations and output.

Let's dive into the solution step by step.

Breakdown of the Code

The initial code attempts to read input values for two numbers (nr1 and nr2) and perform calculations based on their sum, denoted as rs. Below is the structure of the code and its components:

Original Structure

Pin Initialization: Pins are set for input and output.

Input Reading for nr1: Calculates the value of nr1 based on the state of specific pins.

Input Reading for nr2: Here is where the problem lies – there's no input reading for nr2.

Calculation of rs: Adds nr1 and nr2.

Output Logic: Sets output pins based on the value of rs.

Key Areas of Concern

Lack of Input Assignment for nr2: The original code does not assign values to nr2, causing it to always have a value of 0.

Confusing Logic: If the code for nr2 mirrors that of nr1, it would not yield correct results.

Implementing the Solution

To correctly read inputs for nr2, you need to add a similar logic for pin readings used for nr1. Here's a revised approach that you can implement:

What This Change Does

Single Read for nr2: The above code captures the input from pin 9 and pin 10 and converts their state into binary.

Bit Shift Logic: By using the left shift (<<) and binary OR (|) operations, it effectively combines the values from both pins into a single value for nr2, allowing it to hold the binary representation of the input.

Final Thoughts

With the above modification, your Arduino will correctly process the base 2 inputs from both nr1 and nr2, enabling accurate calculations for your calculator project. Remember, debugging your code is an essential skill, and understanding how to manipulate and read inputs can significantly enhance your programming capabilities.

Try implementing this change and observe how it resolves your issues! Happy coding!
