comes to a complete stop no matter the orientation and report quickly .

Welcome back to :kodular:odular,ā€¦
Are you looking for any paid extension developer? If not then may you not be helpedā€¦
Why not to learn develope extension yourself?.. As offcourse we are here to learnā€¦

yes i dont care who it is .

#4

did you already try the accelerometer sensor together with some threshold?

for example in the AccelerationChanged event:

if abs(xAccel) < 0.1 AND abs(yAccel) < 0.1 AND abs(zAccel) < 0.1 
then "phone came to a complete stop"

Iā€™m assuming this is java or something . I only know how to use kodular building blocks .
Thatā€™s why I asked for someone to build a extension . I could not find a way to do it with the blocks that was fast and 100% accurate with rather low CPU usage .

What @Taifun suggested to try is

from what i understand it wont work

the value keeps changing even if the phone is laying on a table .

i have tried this . and get nothing ā€¦

accel
accel1081Ɨ305 71 KB

you can see this in this sample
accel2

here is sample code
testaccel.aia (17.4 KB)

depending on how the phone is layed the numbers are greatly different .

which is why i was asking for someone to build a extension .

#8

now i have tried using the gyroscope sensor . and it seem to be based off velocity
buts its way to sensitive and reacts with bell at the slightest pause ā€¦

gyro

i only want it to make a alert when its stopped for more than 500ms

i see the gyroscope sensor has a timestamp feature but im not sure if this
could somehow be used to detect how long it remained stopped .

any help ?

#9

You can use clock component. Set time interval to 500ms. If conditions are met set clock enabled to true when clock timer show alert

#10

i cant seem to figure it out ā€¦ all i do with the clock is overload my phone and cause it to lock up ā€¦

heres hoping someone can make a extension ā€¦ ill pay ā€¦

#11

No, this is called pseudo codeā€¦
@dora_paz solution is almost correct, the only thing which is missing are the abs blocksā€¦ a value can be positive or negative, therefore you have to check for the absolute value of the 3 accel parametersā€¦

You can find the abs block in the Maths drawer

I think itā€™s good to use an accelerometer, but kodular doesnā€™t have a linear accelerometer, so you have to use an accelerometer that includes gravity, and this sensor generally doesnā€™t have a value of 0,0,0 when not moving. So, do you know calculus? The derivative of a constant is 0,Integrating 0 is still 0.I use these properties, Gravity could be excluded on the accelerometer. seeing once is better than
a hundred words. Hereā€™s a seismometer I made. Take a look and use it in the form you want.

Welcome. Thank you for your contribution
It looks like you forgot to add your exampleā€¦
