Code Examples
Here are a few code examples that demonstrate how to use the 12V Cold White 5050 SMD LED Strip Flexible 5M/Roll Waterproof in various contexts:
Example 1: Simple On/Off Control with Arduino
In this example, we'll use an Arduino Uno board to control the LED strip.
```c++
const int ledPin = 2;  // Digital output pin for the LED strip
void setup() {
  pinMode(ledPin, OUTPUT);
}
void loop() {
  digitalWrite(ledPin, HIGH);  // Turn the LED strip on
  delay(1000);
  digitalWrite(ledPin, LOW);  // Turn the LED strip off
  delay(1000);
}
```
Example 2: PWM Dimming with Raspberry Pi
In this example, we'll use a Raspberry Pi to dim the LED strip using PWM (Pulse-Width Modulation).
```python
import RPi.GPIO as GPIO
import time
GPIO.setmode(GPIO.BCM)
GPIO.setup(18, GPIO.OUT)  # Set pin 18 as output for the LED strip
pwm = GPIO.PWM(18, 100)  # Set PWM frequency to 100 Hz
pwm.start(0)  # Initialize PWM with 0% duty cycle
try:
    while True:
        for dc in range(0, 101, 5):  # Iterate through duty cycles from 0 to 100
            pwm.ChangeDutyCycle(dc)
            time.sleep(0.1)
        for dc in range(100, -1, -5):  # Iterate through duty cycles from 100 to 0
            pwm.ChangeDutyCycle(dc)
            time.sleep(0.1)
except KeyboardInterrupt:
    pwm.stop()
    GPIO.cleanup()
```
Example 3: I2C Control with ESP32
In this example, we'll use an ESP32 board to control the LED strip using an I2C expander chip (e.g., PCF8574).
```c++
#include <Wire.h>
#include <PCF8574.h>
PCF8574 expander(0x20);  // Address of the I2C expander chip
void setup() {
  Wire.begin();
  expander.begin();
}
void loop() {
  expander.digitalWrite(0, HIGH);  // Turn the LED strip on
  delay(1000);
  expander.digitalWrite(0, LOW);  // Turn the LED strip off
  delay(1000);
}
```
Remember to adjust the pin numbers and connections according to your specific microcontroller or board setup.
