When building a basic 6 by 4 LED matrix display, what is the total number of individual LEDs required to complete the grid?
24 LEDs
To determine the total number of individual LEDs required to build a 6 by 4 LED matrix display, we need to understand the structure of an LED matrix.
- Understanding an LED Matrix:
- An LED matrix display is typically structured in rows and columns.
- Each intersection of a row and column in the matrix requires one LED.
- Calculating Total LEDs:
- The given LED matrix dimensions are 6 rows and 4 columns.
- To find the total number of LEDs, multiply the number of rows by the number of columns.
- The calculation is as follows:
\[ \text{Total LEDs} = \text{Number of rows} \times \text{Number of columns} = 6 \times 4 = 24 \]
- Confirming the Correct Answer:
- From the options provided:
| Option | LED Count |
|---|---|
| 10 LEDs | Incorrect |
| 2 LEDs | Incorrect |
| 64 LEDs | Incorrect |
| 24 LEDs | Correct |
- The correct answer is 24 LEDs, which matches our calculated total.
Therefore, to construct a 6 by 4 LED matrix display, 24 individual LEDs are required.
