Final: Final Product and presentation


 Servo wings are stitched into bow of tie

Wire is wrapped around first layer of fabric to hold weight of servo and bow tie


 Another layer of fabric is sewn on to cover wire

Box holds servo, perfboard, and battery

buttons stitched on to be hooked into wires protruding from box

Wire and flexing sensor are feed down through shirt to hand. I learned during critique it is best to have the sensor secured to a part of the body that flexes..


Having a model is always helpful tooπŸ’•πŸ’•πŸ’•πŸ’•πŸ’•

Final: Completed Connection/Circuit









Final: Breadboard to Perfboard


  • I learned to solder a perfboard, and it was an interesting experience.
  • Perfboard
    • a material for prototyping electronic circuits
    • creating ones own circuit board

  • Perfboard first 3 failed attempts 

  • Final Perfboard
    • same positions copied from breadboard, but just placed closer together to create smaller board
Back of perfboard




Front of Perfboard









Final: Flex Sensor Coding and Breadboard





  • Breadboard Testing







Final: Materials


  • Material List

    • One High Torque Servo
      • Adafruit.com


    • One Arduino
      • Adafruit.com


    • One Flexing Sensor Strip
      • Adafruit.com

    • 3 - 4 feet of Solid Core Wire (3- 4 different colors)
    • Breadboard
    • Perfboard

    • 9 Volt Battery

    • Soldering Wire
    • Soldering Iron
    • 100K Resister

    • Patience.

Final: Initial Idea scrapped


  • Initial Final Project idea 
    • movable wings that lit up
      • sensors
        • wind sensor (link to wind sensor in earlier blog posts)
        • flex sensor strip

  • Initial Final Project Idea failed because of improper funds
    • wind sensor did not fit into budget

  • New Idea
    • Rotating bow tie
