Internet of Cars with Electric Imp and OBD-II
Hackaday recently featured the real time car tracker project I designed and built. The tracker uses an Electric Imp module, an STN1110 OBD-II to UART interface and a PA6H GPS module. Vehicle location and engine stats are plotted real time in Google Earth by relaying the data through Firebase to a server written in Python. You can check out the details and build instructions over on Hackaday.
As part of the project I developed a driver for interfacing the STN1110 with an Electric Imp module over UART, available on Github.
