CODING CHALLENGES
MAKE THE SWITCH CHANGE DIRECTIONS: Change the code so
that the position of the switch changes the direction of the motor instead
of turning it on and off.
REPLACE THE SWITCH WITH A BUTTON: Try wiring a button into the circuit
instead of the sliding switch. Now the motor only turns on when you push the button.
REPLACE THE SWITCH WITH A SENSOR: Try changing the code so that the
motor is activated by another sensor, like the photoresistor.
TROUBLESHOOTING
Motor not
spinning
Check the wiring to the motor driver. There are a lot of connections,
and it’s easy to mix one of them up with another. Double check
the polarity of the motor driver. All the text should face the same
direction as everything else.
Switch not
working
Make sure that you are hooked up to the middle pin and one side pin
on the switch, and not both side pins.
Still not
working?
Jumper wires unfortunately can go “bad” from getting bent too
much. The copper wire inside can break, leaving an open connection
in your circuit. If you are certain that your circuit is wired correctly
and that your code is error-free and uploaded but you are still
encountering issues, try replacing one or more of the jumper wires
for the component that is not working.
