ADXLxx TIME WAVEFORM AND FFT SPECTRUM BY ARDUINO AND LABVIEW .10 SAMPLES per SECOND

- in this video we will get real time signal of frequency spectrum from vibration data of ADXL335 accelerometer for three axes.
labview programming to get 4 graphs the first one of time domain signals of (X,Y,Z) directions after calibration process (sub 1.65 base level, and divided by 0.33 sensitivity) the other graphs were of frequency domains spectrum of (X, Y, Z) respectively which be useful to diagnosis or knowing the exactly frequency of the vibrating part.
I FORGOT TO NAME X-AXIS OF THE THREE GRAPHS TO FREQUENCY IN HZ, JUST REPLACE THEM IN GRAPH BLOCKS.

عاشت ايدك يا ذهب ,فديو علمي مفيد جدا ويختصر هواية وكت على الباحثين وان شاء الله ربي يوفقك ويحفظلك الاهل ووالتك ويبارك بيكم

I am using ADXL345 and Aurdino Mega 2560. Is the block diagram same for both of them or are there any changes?. Also send me the code for Aurdino to run in Labview.
Thanks & Regards
will u help me by giving the code?i want to go through the code detail Sir.
باستخدام
LIFA
سوف يعطيني كحد اقصى 10 قراءات في الثانية
للحصول على 300 في الثانية يجب بناء برنامج
C++
داخل الاردينو لقراءة

وارسالها بطريقة

ومن داخل برنامج لاب فيو إزالة

عنها وتكون جاهزة لايجاد التعجيل والازاحة وكذلك

احسنت
ممكن الكود لو سمحت
او الطريقة
Hi Khalid,
ADXL345 is digital accelerometer, how can the same block diagram be used?
If possible please help me out with the changes to be made for this block diagram.
Thank you.
I think the same way
Adxl 335 and 345 are similar
Error 5002 labview...
Can you sample at higher frequency 5-10kz
can i get the code of Arduino ?
Hy, how to use adxl345 with labview?
hallo... how do you have number of 0.023 ?? 0.33 ? 1.613 ?? and for what? thankyou
Hello .....From data sheet of adxl335 you have to read it
khalid mohsin for 0.023 is the formula for FFT? can i know the formula?
rararara yes
khalid mohsin how do you get 0.23?
Code plis
CAN YOU SEND THE ARDUINO CODE?

arduino code
is the Frequency segregation being done for every last 24 seconds?
What you mean last 24 second
@@khalidMohsin yes, as the time is passing with every new sample. You only do the fourier t for the samples in the last 24 seconds
Hai there, i try to do same as you did but there is small problem which the valu of sample is same as the the frequency. Can you explain how you get the frequency value if sample is 50.
Yea u thought right
@@khalidMohsin Is the frequency generate in labview is the right frequency?or just some noise signal? if the the signal is the correct frequency how to confirm it?
@@syafiqnawawi7162 if u read the datasheet of sensor u will read there is effect of noise and temp ... but i think they are so small compared with the harmonic motion i gave . If u look for exactly frequency u need to know ur rotating speed or velocity of harmonic motion.. (RPM )divide it on 60 sec . U will get the the base frequency of motion . Then u will calibrate it in fft u must get the exact frequency . Calibrate process by change sample collection.
@@khalidMohsin hai khalid may i know the unit for the amplitude after calibration
I can't do it. TT
me too
Hi khalid mohsin.
Please check your mail.
Thanks.
محتاج منك شغل اذا تقدر تسويه
I am so busy
Hallo khalid. How if i use adxl345 ? Is it okay ?
U can use the same block exactly
But u must right connect ur adxl345 with arduino
khalid mohsin okay, thanks. I will try.
