I have an idea for an IoT product that may or may not work for niche audience. My background is software, I have developed Dotnet(api), iOS and Android apps and lead engineering teams. Although I have learnt basics of microprocessor, computer hardware etc during my school, I have more or less no knowledge of it now.<p>Where do I get started if I want to learn and make smart IoT products. I want to make a ring with a touch screen and a button. For starters, It will act as a counter using button and remind users(notifications) on particular time of the day.
I also want to develop a mobile app as a companion that will help configure the ring, set reminders etc.<p>Where do one start to make something like this? Are there any open hardware that can be used for the prototype?
