Arduino Capacitive sensing Input/output logic Web serial

Sensor-driven hardware studies

A sequence of Arduino studies covering LED timing, PWM fading, photoresistor input, capacitive touch, servo control, MOSFET load switching, joystick-to-web control, and a final cat-proof charging station.

Final PIR, capacitive touch, LED strip, buzzer, and safety logic.

Context

I explored how physical inputs can shape digital or environmental feedback, starting with simple LED timing and building toward sensed interaction systems.

Process

Each circuit paired a schematic, breadboard implementation, firmware, and operation test. The final study combined a PIR motion sensor, capacitive touch, LED strip, and buzzer into one safety-oriented prototype.

Outcome

The work strengthened my technical fluency with sensors, PWM control, calibration, serial communication, and translating interaction intent into hardware behavior.

Featured prototype Tactile learning Fabric book Soft anatomy

Bloom Fabric Book

A soft puberty education toolkit that turns body literacy, period products, and self-preparation into tactile pages young users can open, touch, and practice with.

Challenge

Make puberty education feel approachable, private, and less clinical.

Prototype

Fabric, felt, stuffing, 3D printing, laser cutting, and sewn interaction cues.

Reflection

The tactile format felt warm and clear; future iterations should reduce bulk and improve durability.

Storyboard for climbing recovery video prototype

Video prototype

Climbing Recovery Concept

A novel interaction for a wellness product communicated through a scenario-based video prototype.

Concept
A bracelet records climbing force, reports session metrics, and recommends recovery timing.
Outcome
Viewers understood the concept clearly because the video made the interaction feel realistic and situated.
