Outcome

Intention

Our goal was to prototype a remake of the lover's cups project, where a photoresistor on a rim of a cup would detect a "kiss" and alert the other person's cup to blink pink. When not "kissing" the cup would remain blue indicating that the temperature sensor was cold. The devices communicated through Wi-Fi connection.

Context

This prototype was based on the Lover's Cups project which involved a couple that has wirelessly connected cups that indicate each other's status.

Process

At first, we tried to connect our devices while having our Photon 2 microcontrollers registered on separate accounts, but we could not find any way to do this. We did not want to use Webhooks, so we then moved our devices to be on the same account. When we did this, at first, we were unable to find a way to push code to the second device, but I found an old thread online about this issue and we used the info from it to troubleshoot our problem.

Our devices blink when the other cup experiences a "kiss".
We can view each other's published events on the same console.

Reflection

I learned how to connect to Particle microcontrollers. I wish there was a way to connect microcontrollers that are on different accounts, and I would look more into this idea in the future.
