Reading Mode

To flash an LED on a Raspberry Pi, you will need to connect the LED to a GPIO (General Purpose Input/Output) pin on the Raspberry Pi and control the GPIO pin using a Python script. Here’s an example of how you can do this:

  1. Connect the positive leg of the LED (also known as the anode) to a GPIO pin on the Raspberry Pi. It is recommended to use a current-limiting resistor in series with the LED to protect the Raspberry Pi and the LED.
  2. Connect the negative leg of the LED (also known as the cathode) to a GND (ground) pin on the Raspberry Pi.
  3. Make sure you have the RPi.GPIO library installed. If you don’t have it installed, you can install it using the following command:
Copy codesudo apt-get install python3-rpi.gpio
  1. Now, you can control the GPIO pin using the following Python code:
Copy codeimport RPi.GPIO as GPIO
import time

# Set the mode of the GPIO pins to BCM
GPIO.setmode(GPIO.BCM)

# Set the GPIO pin you connected the LED to as an output pin
LED_GPIO_PIN = 18
GPIO.setup(LED_GPIO_PIN, GPIO.OUT)

# Flash the LED 10 times
for i in range(10):
    # Turn the LED on
    GPIO.output(LED_GPIO_PIN, GPIO.HIGH)
    time.sleep(0.5)  # Delay for 0.5 seconds

    # Turn the LED off
    GPIO.output(LED_GPIO_PIN, GPIO.LOW)
    time.sleep(0.5)  # Delay for 0.5 seconds

# Clean up the GPIO resources
GPIO.cleanup()

This script will turn the LED on for 0.5 seconds, turn it off for 0.5 seconds, and repeat this sequence 10 times.

I hope this helps! Let me know if you have any questions.
