(+) lead of the 12V quick-connector and then
connect it to the appropriate motor driver
battery terminals. Plug the R/C leads of the
motor driver into the R/C receiver unit, following
the driver’s instructions.
Mount the motor driver and R/C receiver
against the inside wall or near the floor of the
garbage can using double-sided foam tape
(Figure
D
). Mount as low as possible, avoiding
contact with the compressed air tank, battery, or
other components. Mount the receiver antenna
along one of the side walls of the can using
double sided tape or duct tape. The battery
should fit between the mounted motors on the
floor of the garbage can; you can use stick-on
hook-and-loop fasteners to secure it. Solder a
quick-connector to the battery leads.
Plug the R/C relay switch into the receiver.
Using low-voltage connection wire, connect
one terminal of the R/C switch to the positive
lead of the battery (for ease, you may connect
to the positive battery lead at the motor driver
terminal). Connect the other terminal of the
R/C switch to one of the 12V solenoid leads.
To complete this circuit, connect the other
solenoid lead back to the negative (–) terminal
of the battery (or again connect at the motor
driver terminal for ease). Now the solenoid will
open the air valve when the R/C relay switch is
activated (closed).
