Using a Prop Plug, connect programming port
to the PC. Then, connect a 6-9 VDC power
supply to the jack.
Step 15: Connect pin 10 of J7 to the anode
(+) of an LED, and pin 1 of J5 to the cathode
(-) of the LED.
Using the reference above, pin 10 on J7 is
connected to I/O pin P23 on the Propeller.
This is information we will use to run a
sample program.
Step 16: Run this test code that blinks the
LED on I/O pin P23 to confirm operation.
Change the Pin constant and circuit to test
the rest of the I/O pins.
