The following example shows how to set port A0, A1, B2 and B3 pins via JavaScript.
Before being able to set a pin, it has to be configured as an output. Select "Port Settings"
in the menu on the left, and configure Port A0, A1, B2 and B3 as outputs.
</p>
<p>
If the Pin is configured as an input, it's value will be shown by a '0' or '1' character.
</p>
<p>
If the Pin is configured as an output, it will be shown as a button. Clicking on this
button will toggle the pin's state.
