Project 3 Electronic Playground
Electronics is the science of working with
and controlling electricity. This circuit is
shown on the front of the Snap Circuits
®
STEM box, use that picture to help in
building it.
!
WARNING: Moving parts. Do not
touch the fan during operation.
Build the circuit as shown. Set the meter
(M5) to the 1A setting. Place the thin rod in
the electromagnet (M3). Place the glow fan
on the motor (M1). Assemble the build-your-
own electromagnet as per the instructions
on page 5 (or you can assemble it later and
replace the 2-spring socket (?1) with a 3-
snap wire).
Set the switcher (S6) to either side to light
the lamps (L4), spin the motor & fan, suck
the thin rod up into the electromagnet (M3),
and activate the build-your-own electromag-
net. When activated, hold the build-your-
own electromagnet near the compass to
attract the needle. The meter measures the
current.
Hold the magnet near the reed switch (S9)
to light the white LED (D6).
