Add Electronics

Your sea turtle is ready to be outfitted with electronics! We will add the following:

  1. Battery pack
  2. Motors 
  3. CRICKIT microcontroller

Add the battery

Use screws provided to attach battery pack.

 

Mark the position of the two center holes with a pen.

 

Use screwdriver to poke holes in the cardboard. Don't widen the holes too much, the screw threads will grip the cardboard and pull themselves through. 

 

Tighten the battery pack into place. 

Attach motors

 

Mark the position of the motors with a pen or pencil.

 

Use double-sided foam tape to stick motors to underside of turtle.

 

Press hard to ensure strong bond.

Attach CRICKIT

Use twist-ties to hold CRICKIT on turtle's back.

 

Mark the position of two CRICKIT mounting holes.

 

Poke these holes all the way through the cardboard.

 

Thread your ties through these holes, tightening them to hold CRICKIT in place on your turtle's back.

Think carefully about the orientation of CRICKIT on your turtle's back, as you want to make sure motor and power connections are both accessible!

Connect motors

Plug the ends of your motor cables into the terminal blocks on the "Motor" section of CRICKIT. 

Tighten these connections down with a screwdriver.

Make sure to load up your turtle with fresh batteries. These motors can get power hungry and your turtle may have trouble getting around if your batteries are low.
