Hi Mathew,

The way you have your circuit connected, sounds like your input pins are
floating.

Connect the resistors between the port pins and +5V. Then connect one
side of the switches to the port pins and the other sides to ground. The
port pins are now held at a 5V potential, and if you read them, each one
will be at logic 1.

When you press the switch, the port pin is connected to ground, and it
will register as a logic 0 when you read it.

To read PortB
