new_contents: # Sensor Sleep Mode Example.
  # This example demonstrates the sensor sleep mode. The sleep mode saves around
  # 40mA when enabled and it's automatically cleared when calling sensor reset().
  
  import sensor, image, time
  
  sensor.reset()                      # Reset and initialize the sensor.
  sensor.set_pixformat(sensor.RGB565) # Set pixel format to RGB565 (or GRAYSCALE)
  sensor.set_framesize(sensor.QVGA)   # Set frame size to QVGA (320x240)
  sensor.skip_frames(time = 3000)     # Capture frames for 3000ms.
  sensor.sleep(True)                  # Enable sensor sleep mode (saves about 40mA).
