This model will show which quadrant a coordinate belongs to. When a coordinate is selected, the correct quadrant LED glows (Quadrant I / II / III / IV).

How the Model Works (Simple Explanation)

1. Each nail represents a coordinate like (3,4), (-2,5), etc.
2. Each coordinate belongs to a specific quadrant.
3. When you touch the nail with the probe:
 ✔ The correct quadrant’s LED glows automatically.
4. This shows whether the coordinate has:

Positive x, Positive y → Quadrant I

Negative x, Positive y → Quadrant II

Negative x, Negative y → Quadrant III

Positive x, Negative y → Quadrant IV
