Examples for using Raspberry Pi in IOT with various Input and Output devices

What is Raspberry Pi ?

It is a small single board computer that can be used for learning, programming and for developing projects based on IOT or embedded systems.

Basics of GPIO Programming on Raspberry Pi

• To import the Raspberry Pi module use from RPi import GPIO

• To set the mode to BOARD numbering system use GPIO.setmode(GPIO.BOARD)

• To make the pin as input pin, use GPIO.setup(PIN_NUMBER, GPIO.IN)

• To make the pin as output pin, use GPIO.setup(PIN_NUMBER, GPIO.OUT)

• To take input from the pin, use GPIO.input(PIN_NUMBER)

  When the input is given, the value returned by the function will be 1 else it will be 0

• To give output to the pin, use GPIO.output(PIN_NUMBER, OUTPUT_VALUE)

  • To make the value high, use GPIO.HIGH in place of OUTPUT_VALUE
  • To make the value low, use GPIO.LOW in place of OUTPUT_VALUE

• Note:- Change the PIN_NUMBER to the required pin number value
