Hello Alex

I have been able to use the sr04 with comport but not with standardfirmata

the problem is that i need to sacrifice and entire controller and a bluetooth

connection in order to handle the sr04 instructions all by themselves and this is not elegant.

it could be nice to have a mekanism where the trigger and eko processes will give a

range distance result from 0 to 1(firmatas format) into an analog input so that it could be handled

with the rest of the sensors, or into an digital IO if that is not possible without electronics.

cheers
