Open Project – Light Step


My concept is to create a shoe with two analog pressure sensors on the bottom. Most people walk differently then other, when some people run they only step on the toes while other use roll from the heel to there toes. The inputs are the two separate analog pressure sensors, and the CPX will display the output as LEDs. Originally I wanted to use three sensors and 3 corresponding single LEDs that would increase in brightness during increase in pressure, but there wasn’t enough connections on the CPX to achieve that and its harder to see the pressure change with just the brightness increasing.


To represent and analyse, through lights, how you step and see how much pressure you apply n your heel compared to your toes when you step. Can also compare your step to another persons step.


I first started with following Variable resistors workshop to create the analog sensors.





For the code I just adjusted the Variable Workshop code to work for two sensors and changed how the lights function.

I then layed out the circuit and successfully tested the sensors.screenshot-2021-04-01-182700

I then started sewing the CPX to the shoe and extended the flaps on the sensors to secure them to the bottom of the shoe by taping the flaps to the sides of the shoe.

I then sewed the two resistors on either side of the shoe and connected them and the CPX to the sensors with conductive thread. I had to use two wires in order to not run the conductive thread onto each other because there were only certain parts of the shoe I could sew into.



In order to conceal all the parts and wires I cut out a sock to fit around the shoe while leaving the sensors uncovered and leaving the CPX open to be covered with tissue paper to defuse the LEDs while still be able to see each light on it own when lit.

Reflection: I think the final product communicated the idea and concept clearly but it could function more accurately and the aesthetic of the sock doesn’t make it look very nice.  If I were to do it again I would use a much thinner shoe in order to be able to sew the conductive thread into anywhere on the shoe, because the one I used limited the space the thread could be. If I had a shoe with that space and a CPX with more analog pins or a second one in order to accomplish my initial idea of using three sensors (add one to the center of the sole) and with there own corresponding LEDs that could all be on at once representing the pressure with brightness but the LEDs I have made hard to distinguish between ranges of pressure. I also think the sensors could be built better but my sewing experience limited me in making it function perfectly and more accurately.

Assignment 2: Expressive Wearable – Tears

Concept & Objective – The idea was to create a hat that ether alone or in public can represent sadness or tears. While at the same time creating an aesthetically pleasing look that in darkness can simulate flashing tears across someones face. One blue light blinks and stops then a second LED blinks as if a tear was moving downwards.

Process – I started by drawing the circuit on paper and then creating it on its own using wires and a basic switch and creating the code for two lights blinking after another.



I then began sewing with regular thread to secure the fabric hanging off the hat that is meant to hold the LEDS. Then began sewing with the conductive thread.

Then used blue tissue paper to mach the LEDS and encase them, but it also helps with the effect. Then used a large piece of conductive fabric in another hat to encase everything and complete the circuit when pressed against.

Parts List:

  • Circuit Playground Express
  • Conductive Thread
  • Regular thread
  • 2 Clothes Pins
  • Conductive Fabric
  • 2 resistors
  • 2 LEDS
  • 2 Tuques
  • Tissue Paper

Reflection – The sewing was the hardest part. I had to restart twice because of conductive thread being to loose and connecting with another line of conductive thread and parts just falling off because it was hard to secure them properly. I also found great use of of mapping the circuit out with the normal wires and following that as I sewed and constantly checking with the real wires connecting them when I only had some of the parts sewn in and just checking with a wire before I used thread to make sure each step there wasn’t a mistake.

Assignment 1: Speculative Wearable


My wearable is meant to provide a physical and visual representation of your heart (pulse). It reads your pulse from your wrist as any other fitbit or smartwatch can do. In reaction to your pulse in the wearable will inflate and deflate in sync with your heart rate in real time. As Well as a pedometer correlating with the lights on the wearable in green, yellow, or red to represent if your heart rate is too dangerously high or slow based on how you’re moving.


The objective of this wearable is to provide haptic feedback and visual language to help understand or feel or see a part of your body that is well hidden. It could help with breathing and calming yourself being able to give a greater feedback feel in order to assist with breathing if you have anxiety issues and just a greater awareness of your body.
