 7  # Wire the circuit as follows:
 8  # 1) connect anode (+) lead of LED to P1_33 pin
 9  # 2) connect cathode (-) lead to 1K Ohm resistor
10  # 3) connect that 1K Ohm resistor to GND
11  #
12  # NOTE: the pin mode can be verified with the command line
13  # utility config-pin on the BeagleBoard.org Debian image
14  #
15  # To verify the pin is in GPIO mode:
16  # debian@beaglebone:~$ config-pin -q p1.33
17  # P1_33 Mode: gpio Direction: out Value: 0
18  #
19  # To set pin to GPIO mode:
20  # $ config-pin p1.33 gpio
