Project 15
Snapino
™
Test
This circuit tests the snap
connections on the Snapino
TM
module (U31), and is referenced by
the Advanced Troubleshooting
procedure on page 8. Build the circuit
as shown, leaving one end of the
white jumper wire unconnected for
now. Load sketch Snapino_Test into
Snapino
TM
using the programming
instructions in project 3.
The green LED (D2) should be on.
Connect the loose end of the white
jumper wire to each of the unused
snaps on the Snapino
TM
module
(U31), one at a time; the red LED
(D1) should be blinking each time.
Remove the USB cable, then connect
the 9V battery holder and turn on its
switch; the circuit should work the
same as with the USB cable.
Programming Note: This sketch sets
each connection on Snapino
TM
to be an
output, then toggles each on and off.
