So, Arduino is powerful! You can make all sorts of crazy things with it. I needed a remote monitor for my motorbike. Originally, I wanted a wired monitor, but there's little point messing about with them now when everyone has phones. Why pay £3 and do a load of unsightly, fragile and temperamental wiring when everyone has bluetooth and a screen? Specifically, this video demonstrates the project. A remote monitor that presents voltage of a battery and also temperature from a thermistor.
