“Zerynth App is a mobile application for Android and iOS that allows fast prototyping of graphical interfaces for your IoT projects. With Zerynth App you can turn any mobile into the controller and display for smart objects and IoT systems! In particular, you can manage and control the connected devices programmed with Zerynth, enabling a bidirectional communication channel between them and your mobile. In this tutorial, we’re going to see how to develop a simple but powerful IoT thermometer, using a Zerynth-powered single-board microcontroller and Zerynth App as the remote display.”
