Electronics/Robotic 10

Electronics/Robotics 10 is a 2 credit course designed to introduce students to the world of electronics & robotics. This year, the course will run every other day for the first term (approx. 60 hrs). Students will begin by breadboarding simple circuits and in doing so will learn what some of the more common components do. Arduino ‘microprocessors’ will be introduced which will allow for the exploration of programmable electronic control.  Projects will follow utilizing skills learned along with introducing students to manufacturing processes.

Course Outline Electronics 10

Below you will find a number of resources and materials that will be used for the course. Also, look under Resources on the Electronics Drop Down Menu for additional information on electronics.

BREADBOARDING (Level 1)

video – What is a ‘breadboard’? (Youtube)

Breadboarding – Student Answer Booklet – You will be given this. 
DON’T lose it as it is used for marking purposes.

Useless Box Project (Level 1)

The Useless Box is a simple and fun little project that teaches students the various processes/stages of taking a project from conception to completion.  Students will breadboard the circuit, program an Arduino Nano to make the circuit work, create a printed circuit circuit board, design a case in Inventor, 3D print the case and finally assemble it all together to create a professional looking project.  See youtube video of it in action HERE.

Obtain a PCB, and using a Dremel drill press, drill all holes
Obtain and solder in all components

3D Print The Servo Finger And Door Hinge

You will need to 3D print a servo finger to turn off the switch.  The ‘.stl’ file can be found on the school share, under ‘Maker Woodwork students’.  Look for the ‘UselessBox’ folder.

You will also need to 3D print a hinge for the door.  The .stl file for this is in the same folder as the finger.  Do not print the hinge and the finger together on the same printer.

Cutting The Box Parts

You will find the .emf file for the box in the same folder as the model files for the 3D printed parts.  ‘Import’ this into the laser software.  Adjust the laser’s ‘settings’ to cut 1/8″ Baltic Birch Plywood and focus the laser to the surface of your plywood.  Check and double check (focused?, positioned?, settings correct?, fume extraction on?, nozzle air supply on?)…then cut.

Assembling the Box

  1. Block sand the faces (not the edges) of all visible components to remove residue/smoke from cutting.
  2. Test fit the box parts.  The fit should be snug. 
  3. Identify the key areas to be glued (no, the whole box doesn’t need glue)
  4. Use a paint brush to apply glue to key areas as you assemble the box. WASH THE BRUSH IMMEDIATELY AFTER THIS STEP!!!
  5. Allow time for the glue to dry (minimum 1hr)

Final Assembly

  1. Use either the screws that came with your servo, or #4 x 1/2″ wood screws, to attach the servo to the servo bracket.
  2. Use a small amount of glue (get from the teacher) to attach the hinge to the box.
  3. Assemble all components inside being careful to avoid interference with the servo/finger operation.
  4. Attach the bottom to the box using #4 x 1/2″ wood screws

OTTO (Level 1 and/or Level 2)

Students will build and program this small little robot called OTTO.  It will be able to walk and avoid obstacles and hopefully dance to music!!
