Skills Dev V: Working with Networking

Intention

In this project I worked with my team to re-make Kiss Communicator.

Context

The Kiss Communicator connects people across distances. Users blow into it to send a "kiss" as animated light patterns. The recipient’s device signals the message, which plays once when squeezed, making each "kiss" a fleeting, meaningful gesture.

In this small prototype, we simulated the breath to light conversion and send light signals to a different device.

Process

Testing with wind sensor
Adding wind sensor input and light sequence output via neopixel
Testing publish/subscribe events with an LED on a single device
Testing publish/subscribe events with webhook between two devices
Separate input and output to two devices using webhook

Outcome

We successfully created a prototype that translates breathe data to light sequences. Currently it's one direction including a publisher and subscriber.

Reflection

Using different light states as user feedback to indicate different actions
Sending data between different devices with webhooks
