Using what we learned from the motor card, we produced an application example. This example uses the wire coil as the motor for a paper car. We also used capacitive touch to make the motor go.
First, you take the corner of a motor card that has a tower and attach it to the top right side of the design card. Tape this section like the motor card. Then, you put some copper tape on A7 and arrange it to be the “gas pedal”. This is what it would look like:
After that, you draw the right and left profile of a car along with 2 rear wheels and some supports to glue it together. We used hot glue to make the car 3D. The supports are the same width as the tower so that it fits over the top. The two small supports are bent into an L-shape and glued to the inside of a car profile piece right above the rear wheel. It is supposed to contact the peak of the tower and keep the car structure elevated.
Poke small holes into the wheel cutouts, and hot glue one onto the motor coil. Place it into the slot in the tower and glue the other wheel on. It should look like this:
Place the 3 magnets under the tower and place the car structure over the tower so that the wheels line up with the wheel slot. Upload this code https://makecode.com/_fp07b9WThe7x.
If you press the “gas pedal” the wheels should spin. It might need a little momentum to get it going.
