Services are the software apps we use every day to connect with physical objects and obtain data from mobile devices. The gateway to managing these services for physical connectivity can be achieved by using applets with embedded hardware.
Researchers have developed a floating, piston-driven engine that generates electricity causing a light to flash, and a rotary engine that drives a miniature car, both using the power of evaporating water.
There are variety of WiFi-based chipsets that embedded developers and product designers use in their IoT designs. An alternative reference design that allows these developers and designers to explore IoT concepts is the cloudBit manufactured by littleBits electronics.
