* 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.

|
## Rasberry PI Basics Example
|
|
```python
|
|
## 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()
|
|
```
