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.

Useless Box – Laser Cut

Useless Box Project Procedure – Electronics Portion
Useless Box Marking Rubric

Making the Circuit Board – DipTrace
Using DipTrace – Library Setup
Making the Schematic for the Useless Box  (print and submit your schematic)
Making a PCB layout – setting up the program for use
Making the PCB for the Useless box (print and submit your design)
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 > Electronics-Robotics 10 > Useless Box’. 

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.

Setting up the 3D Printer/Printing

Cutting The Box Parts

  1. On your computer open Universal Laser Systems ‘UCP’ (User Control Panel
  2. Near the top of the UCP is a folder icon – open it
  3. Choose ‘Import’ and navigate to “H” Drive (the shared drive) and the folder  ‘MAKER WOODWORK > Electronics-Robotics 10 > Useless Box’
  4. Select/open ‘boxFile.emf’ (you should now see the parts in the UCP)
  5. Obtain a piece of 1/8″ (3mm) Baltic Birch plywood – at least 8″ x 8″
  6. Take your computer to the laser.
  7. Prepare the laser to cut your material
    1. Focus the laser to the surface of the material
    2. Ensure the material is placed such that the cut will be on the material
    3. Turn on the air supply for the nozzle (red and yellow valves on the wall)
    4. Turn on the fume extractor
    5. Run the laser

**Note – if a part fails to be fully cut, individual parts can be found in the subfolder 

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)

Completed the Useless Box?  Yes!  Then it’s time to build Otto.

Follow this Instructable to get your robot up and running.  It will detail how to 3D print your robot.  You will be given MOST of these parts, but you do have to print some so you can learn/confirm the process.

3 x 3 x 3 LED Cube (Level 2)

LED Cubes are fun to make and can be mezmorizing to watch.  Sizes can range from the minimal 2 x 2 to extremely large.  This 3 x 3 cube you will make involves 27 LEDs and is simple enough to qualify as suitable for a first effort, but complexed enough to be interesting when completed.

Follow this instructable to begin building your cube.  We be breadboarding the circuit first and once successful, constructing a project enclosure to display this fragile sculpture.
