# Arduino_LED_Control
2+
23
An Arduino project demonstrating various LED control techniques, including blinking, random color generation, secondary color creation, random 16 million colors, and brightness control.
4+
5+
## Features
6+
7+
This project uses an Arduino to control RGB LEDs through various functions. The code allows you to:
8+
9+
- Blink LEDs in a sequence
10+
- Randomize LED colors
11+
- Generate secondary colors by combining primary colors
12+
- Produce random colors within the 16 million color range
13+
- Increase and control the brightness of LEDs
14+
15+
