 make sure the mode for all GPIO pins you want to test have a Mode of IN
 if not, set the mode for each.. 
 
-# set BCM pin 4 as an input
-gpio -g mode 4 input
+set BCM pin 4 as an input

-# zero when nothing is connected to the input 
-gpio -g mode 4 down

+This will show you the output of gpio readall every 2 seconds. This way you can concentrate on
+moving a wire to each gpio pin and then look up to verify V has changed as you expect without
+having to type.

 connect a 3V3 pin in series to a 1k ohm resistor
 connect the other end of the resistor to each gpio pin
 when it is connected V should be 1
