* Created a file for "Basics of Raspberry Pi Stuffs" The code contains two parts: First part is simply blinking led (Blink time can be set by time.sleep(x) x for the number of seconds) Second part is for pwm control for led brightness * Update RaspberryPiBasics.py * reformatted two 2 space indention with title corr.

## CODE THAT MAKES AN LED GLOW FOR 2 SECONDS
import time
import RPi.GPIO as GPIO
while True:
GPIO.output(2, GPIO.HIGH
time.sleep(1)
GPIO.output(2, GPIO.LOW)
time.sleep(1)
## CODE FOR PWM CONTROL OF LED BRIGHNTESS
import RPi.GPIO as GPIO from time
import sleep led_pin = 2
GPIO.setmode(GPIO.BCM)
GPIO.setup(led_pin, GPIO.OUT)
pwm = GPIO.PWM(led_pin, 100)
pwm.start(0)
try:
while True:
for x in range(100):
pwm.ChangeDutyCycle(x)
sleep(0.01)
for x in range(100, 0, -1):
pwm.ChangeDutyCycle(x)
sleep(0.01)
except KeyboardInterrupt:
pwm.stop()
GPIO.cleanup()
