The website GPIO control
This HTML code uses the website as input form and output element alike. If you
look at the form element, you can see that a number of input elements of type
checkbox are used. They are assigned an individual name that is derived from the
pin name. The placeholder in the text is the text *checkedX* in each case. When
the pin is low, the placeholder is simply deleted. When the pin is high, the program
will replace *checkedX* by CHECKED, which will cause the checkbox to be dis-
played with a checkmark when loading. This time, there is a button that must be
clicked after selecting the right boxes to transfer the form.
