Are there any neat ways to display the movements in RR?
From my Sony Xperia
X is reading virtually 0G (1.6v), Y is reading virtually 0G (1.6v) and Z is reading 0.4G (1.73v) when held level. I was expecting Z to be 1G so I need to do some reading up.......... Enjoying learning what the Brain can do :).
well, 1G is not actually correct anyway. and depending on the design of the sensor, there could be good reasons why its not showing 1G.... there are some other force's , because of earth's rotation, that in macroscopic level don't seem important, but they could affect the sensors readings... but again, you do not care about the "Actuall" force that the sensor is sensing. only the difference in output, in regards to "Zero". i would, just use the "1.73v" as 0G... ;)
(the 1.6 v on X and Y, are there becouse there ARE forces on those axis too. but they are constant, like gravity, so you should not care, hence the "virtuall zero" )
I was thinking along similar lines about calling straight and level readings as 0 :).
What app are you using to display the data?
From my Sony Xperia
e well... i print through serial, all the info i want (Fuel, speed, accel), and then, have a a tablet, mounted as speedometer. i have written an app, to simulate a speedometer, but i dont know , any of-the-shelf solution.. :/
I'm new to FB so my answer is more directed at how microcontrollers (MCs) generally work - First, most (not all) flavors of Arduino are 5v and the related sensors are the same - most MC's will not tolerate (i.e. they can burn up) voltage higher than their control voltage AND when using lower volt sensors you lose around 30% of the sensor 'resolution' - that said, as I understand it the FB is substantially more tolerant of mismatch voltages, but in order to get the most out of your sensor and, by proxy out of your FB I would recommend using a signal voltage adapter - this is sold as a 'Logic Level Converter'. Some are unidirectional and some are bidirectional so make sure to get one that matches your requirements.
You could also get sensors that are the correct voltage - such as those for Raspberry PI and actually for a vast majority of MCs - Arudino's are an oddity in the sense that few MCs operate at 5v (or at least far less than operate at 3.3)
Last bit of my 2 cents - most MC's, even if tolerant of higher-than-normal signal voltage will, when faced with 'out of spec' voltage, start acting unreliably and outputting a lot of 'garbage' readings - in other words, it is like if you turn your stereo up way louder than the speakers are designed for - they may survive but what you are listening to in the mean time is a lot of static, hisses and pops - i.e. not 'clean' sensor readings.
