title: the output of accelerometer sensor adxl335 connected to raspberry pi is 1. How to get the output in decimal format
body: <p>I have written the below program in python and tried to read tthe accelerometer sensor output. When I print the output of the accelerometer I am getting 1. Please advice me how to get actual output in digits to know the exact tilt of the accelerometer. </p>
  
  <pre><code>import RPi.GPIO as io # import the GPIO library we just installed but call it "io"
  import time
  io.setmode(io.BCM)
  io.setwarnings(False)
  
  x_axis = 17 # this is the GPIO number our accelerometer's x axis is connected
  y_axis = 27 # this is the GPIO number our accelerometer's x axis is connected
  z_axis = 22 # this is the GPIO number our accelerometer's x axis is connected
  
  io.setup(x_axis, io.IN) # initialize receiver GPIO to take input
  io.setup(y_axis, io.IN) # initialize receiver GPIO to take input
  io.setup(z_axis, io.IN) # initialize receiver GPIO to take input
  
  try:
      while True:
          x = io.input(x_axis)
      if x:
          print"x-axis ="
          print(x)
          time.sleep(1)
  
          y = io.input(y_axis)
      if y:
          print"y-axis"
          print(y)
          time.sleep(1)
  
          z = io.input(y_axis)
      if z:
          print"z-axis"
          print(z)
          time.sleep(1)
  
  except KeyboardInterrupt:
      print("Received Interrupt")
