Lab 5: Paired Devices with Webhooks

Outcome

Connect multiple argon devices. The major function is that one can let the other's neopixel turn into red when he/she wants to convey information through this color changing.

Process

The purpose of this lab was to connect multiple argons with the help of Webhooks. The main issue the team encountered during this lab was with Webhooks. In the portion of the device ID, one team member placed their device ID instead of another teammate's ID. Once this error was discovered, both argons ran the code perfectly. This concept of connecting argons can be very beneficial for our team's GlowCap project to connect our cap with our hub.

Reflection

Our team learned a different way to connect multiple argon devices. The team has used the Blynk IoT platform to flash or message code to another device, specifically Arduino. Compared to Blynk, Webhooks is much easier was much easier to use and will result in the team using it for the connection of multiple devices.
