By: prayag nao Today we are going to discuss about simple I/O program of raspberry pi.here is pin diagram of raspberry. so we are going to talk about GPIO I/O program then we need 2 pins,one for output and one for input from button. material required: Raspberry pi. A push Button. some connector wires. A LED. connections: connect 5v pin of raspberry pi to one pin of push button. Now connect one end of push button ti 11th pin of raspberry pi. Now connect 13th pin to +ev pin of led and ground to -ev pin of led (you should use a resistance of 330omhs in series with LED). Programming: open text editor of raspberry pi and paste the following code. import GPIO.RPi as GPIO ##import GPIO library import time GPIO.setmode(GPIO.BOARD) ##use board pin numbering GPIO.setup(11,GPIO...
