I setup a Pi with a car backup camera monitor and push button. It's for displaying a to-do list that I cycle through by pressing the button. I wrote it for the command-line so I don't have to use X-server to save on cpu usage. Unfortunately I can't read the text. Any suggestions on making the text big enough to read 3 feet away?
# Import the required module. import RPi.GPIO as GPIO import os # Set the mode of numbering the pins. GPIO.setmode(GPIO.BOARD) # GPIO pin 3 is the input. GPIO.setup(3, GPIO.IN) def clear_console(): os.system('clear') i = 0 to_do = ['Take out trash', 'Vacuum', 'Put papers away', 'Put books away', 'Put electronics away', 'Put pens away'] clear_console() print to_do last = 0 while 1: if not GPIO.input(3): if last != 0: clear_console() i += 1 if i < len(to_do): print to_do[i] else: print "Congrats! You're finished." last = GPIO.input(3)
