Blink led example arduino with python

To blink an LED with an Arduino using Python, you will need to:

1. Connect the LED to the Arduino board. You will need to connect the positive leg of the LED (the longer leg) to a digital output pin and the negative leg (the shorter leg) to a ground pin.
2. Install the PySerial library, which allows Python to communicate with the Arduino over a serial connection.
3. Use PySerial to send a command to the Arduino to turn the LED on and off. You can do this by opening a serial connection to the Arduino and sending a string with the command you want to execute.

Here’s an example of how to blink an LED connected to digital pin 13 on an Arduino Uno using Python:

import serial
import time

# Set up the serial connection to the Arduino
ser = serial.Serial('/dev/ttyACM0', 9600)

# Blink the LED on and off
while True:
ser.write(b'13H') # Turn the LED on
time.sleep(1) # Wait 1 second
ser.write(b'13L') # Turn the LED off
time.sleep(1) # Wait 1 second

# Close the serial connection
ser.close()

This code will turn the LED on for 1 second and then off for 1 second, creating a blinking effect. You can adjust the delay between turning the LED on and off by changing the time.sleep() duration.
