first of all, i wanted to say i'm sorry for not updating this project that often.
right now i came across a new bluetooth module, namely a ble113 module, which is bluetooth low energy, and has very low power modes (to a few hundred nA).
compared to a hc06 it is about 1/2 the size, and consumes way less power.
this also results in a smaller pcb size (in theory).
i haven't gone further with coding as of now. but i will resume coding soon (hopefully within a week)
yes, this project is far from dead!
offtopic: i just looked at the time here, 3:45AM, i should go to bed now. :P
that's it for this update.
