Blink LED using ESP32 python program in IoT

Blink LED using ESP32 python programe in IoT

                    In this programe, we will see about LED turn on & off procedure using ESP32 microcontroller and Python Program.

Requirements,

• ESP32 Microcontroller
• LED
• 10 Ohm Resistor

Circuit connections as,

• ESP32 pin2 to one end of Resistor
• Resistor another end to LED positive
• LED negative to ESP32 GND(ground)

Python script:

Turn "ON" LED:

print('Turning on the LED')

from machine import Pin

# Define the pin where the LED is connected

led_pin = 2

# Create a Pin object for the LED

led = Pin(led_pin, Pin.OUT)

# Turn on the LED

led.on()

Turn "OFF" LED:

print('Turning off the LED')

# Turn off the LED

led.off()

Turn "ON & OFF" in Loop:

import time

from time import sleep

while True:

    led.on()

    time.sleep(1)

    led.off()

    time.sleep(1)

*simulate in wokwi before the physical working

Full programe for turn ON & OFF

print('kavi-Turn on&off the LED')

from machine import Pin

import time

from time import sleep

#Define the pin where the LED is connected

led_pin = 2

#Create a Pin object for the LED

led = Pin(led_pin, Pin.OUT)

#Turn on the LED

led.on()

#Wait for 1 second

time.sleep(1)

#Turn off the LED

led.off()

#loop on&off

while True:

    led.on()

    time.sleep(1)

    led.off()

    time.sleep(1)
