Using an alligator clip connect pin 7 to the free end of the
1KΩ resistor attached to pin 8.
Using two microclips connect pin 8 to one end of the
switch, and pin 4 to the same end of the switch. (Put one
hook inside the hole and the other hook around the whole
connection. Check to make sure they are securely con-
nected.)
Use an alligator clip to connect the free end of the other
1KΩ resistor (by pin 3) to the bolt.
Twist the free end of the 3.9KΩ resistor around the plus
end of the
LED. Connect
the minus end
of the LED to
the grounding
bolt using an
alligator clip.
Connect pin
number 1 on
the chip to the
grounding bolt
with an
alligator clip.
Attach an alligator clip to the outside of one of the bolts.
Attach the other end to a handhold (copper pipe). Do the
same for the other bolt and handhold.
Connect the minus end of the battery (black wire) to the
grounding bolt with an alligator clip.
10.Connect the plus end of the battery (red wire) to the free
end of the switch using a microclip lead. If the LED lights
up you know the switch is ON. If it does not, flip the
switch and see if the LED lights. Label the switch clearly.
If you cannot get the LED to light in either switch position,
you must double-check all of your connections, and make
sure you have a fresh battery.
