Prolific Hack a Day author [Mike S] has been playing in his lab again and he’s come up with a neat way to talk to microcontrollers with an LCD monitor. The basic idea behind [Mike]‘s work isn’t much different from the weird and/or cool Timex Datalink watch from the 1990s.
This build is very similar – and was inspired by – an earlier post about microcontroller communication with flashing lights. Still, [Mike]‘s build reminds us of the strangely futuristic Ironman watch we had in ’97. Check out [Mike]‘s demo of his computer/micro comm link after the break and his code on github.
