A Particle Argon MCU reads data from a capacitive soil moisture and communicates that data to an iOS app using Morse code.
In this project, I will share some of the techniques used by my low-cost robot car projects.
I bought the Google AIY Voice Kit to compare it with Amazon Echo, and see what platform is easier to develop an IoT app using Particle.
AWS-IOT provides server-side state management for applications where the Particle is asleep most of the time, i.e. battery powered.
The "Monitor and Command" VS2015CE solution provides the blocks to build distributed monitor/command UIs for embedded projects.
