title: Second button is not working Raspberry pi pico
body: <p>I'm new in micropython and I'm following the book about Raspberry pi pico. And I just wanted to know, how can I just make led ON if button1 or button2 are pressed.
  Here is my code, and only the first button works, I checked, both buttons are not broken, but the second only shows the value 0 in this code.</p>
  <pre><code>from machine import Pin
  led = Pin(15, Pin.OUT)
  button1 = Pin(14, Pin.IN, Pin.PULL_DOWN)
  button2 = Pin(16, Pin.IN, Pin.PULL_DOWN)
  while True:
       if button1.value() == 1 or button2.value() == 1:
          led.value(0)
       elif button1.value() == 0 or button2.value() == 1:
           led.value(1)
  </code></pre>
