Building IoT With Arduino

Abstract

IoT tools and techniques can be split into three main categories – infrastructure (i.e. hardware like Arduino Uno), software apps (e.g. Arduino C/C++ sketch), and lightweight protocols (e.g. MQTT and CoAP) for the connection of the heterogeneous components. Nowadays, they allow to develop fully functional smart systems. In this chapter, Arduino open-source computer soft- and hardware are discussed for the remote LED control, the web-server development, the design of the dual axis solar tracker with energy saving algorithm, the smart city's natural environment component based on Arduino weather station, the aid systems (in the mobility) for the visually impaired and blind people. In addition, the connection of the heterogeneous soft- and hardware is presented based on MQTT protocol.
