IOT Experiment using Raspberry Pi and other Devices

Test LED working or not by giving to Power.

If working remove and place it in GPIO Pin

led             anode            cathode

        resistor one end    gnd(6 or 9 or 14)

resistor other end: GPIO PIN(12,11)

->Led Anode(LargeLeg)with Resister 1 Leg

LED Cathode (Small Leg) with GND

Register another leg with GPIO

Code:-1

To import Raspberry from python

import RPi.GPIO       //Using library's in Commands

import time   //for giving delay

import RPi.GPIO as h //Short cut for reusing reducing length

h.setwarnings(False)  //to avoid warinings

led=12

h.setmode(h.BOARD)  //Board Mode (Sequence Numbers) or BCM MODE   RED GREEN

h.setup(led,h.OUT)

h.output(led,1)

print("led on")

time.sleep(5) //given delay for lite to glow for every 5 seconds

h.output(led,0)

print("led off")

Code:-2 For Continues looping using while

To import Raspberry from python

import RPi.GPIO       //Using library's in Commands

import time   //for giving delay

import RPi.GPIO as h //Short cut for reusing reducing length

h.setwarnings(False)  //to avoid warinings

led=12

h.setmode(h.BOARD)  //Board Mode (Sequence Numbers) or BCM MODE   RED GREEN

h.setup(led,h.OUT)

while 1:

    h.output(led,1)

    print("led on")

    time.sleep(5) //given delay for lite to glow for every 5 seconds

    h.output(led,0)

    print("led off")

            time.sleep(2)
