I thought the video was, well thought out and implemented. It was a joy to watch, thanks.

great explanatory video, the step by step walk-through made things very clear!

Very clear detailed and focused tutorial,Thanks a lot Sir..

Well Done!! Great detail walking through the code. Thank You

Accellerometer measures force acting on the object so the z is actually pointing down and force that it measures points up when object is steady on a surface (it actually measures the static force applied by the surface). You can check by movement. X is front, y is right and z is down.

OOOOWWWWWW ! Thank you very much! Thanks to you I did not burn another device.

Great tutorial m8! Saved me a lot of time! :)

Great video, thank you.

great video buddy

Great video! Can anyone tell me why you're using 5v? All the documentation I've read for the ADXL345 tells me 3.6v is the maximum input.

can i connect the ADXL 345 to arduino uno using wireless conection?? planning to build my project and i want to use the acclerometer in my wireless controller

Thanks for posting this. I'm still trying to get mine to output anything. The SDO pin should also be pulled high (or low) according to the datasheet. The ALT ADDRESS (SDO) pin be connected to either VDD I/O or GND when using I2C.

Turns out the first one I purchased was evidently bad because the second one worked as advertised. Thanks again for the video!

i am working with MMA 7660FC accelerometer and i got the values but not changing the axis values when moving the sensor . can help me ? what is the problem can give any suggestions?

Thanks alot! Great video! But this gives orientation and I want the XYZ forces... How can the code be modified for this??

Superb video once again. what range have we set +-16g, +-8g, +-4g or +-2g??? how can i change this range ?

Thank you

Hey sir, nice tutorial. Is it necessary to use a resistors on the diagram? What will happen if we dont use the resistor? Thanks before.

Big Like :) thanks but i want to ask some thing isn't the auto sleep bit is zero by defult ? ie:disabled by defult ?

Thank you very much great video! Maybe you can help me understand why randomly the printf (meaning all the data stream) just stops coming in?? The communication just stop and when i reset the power it sometimes restart the code sometimes not. When i pull out and and back in the SDL or SCL also sometimes helps and restart the code. I double checked the set up, i used the same resistors as you .. Hope you can help me out thanks!

Hi, i need help on how to use 2 accelerometer on a arduino mega. i tried pluck in both to the SDA and SCL ports. but their readings add up together, how do i see each accelerometer readings individually?

can it be used for vibration analysis ?

Hello, thank you for this Tuto. I need to mesure a linear acceleration from a objet that will move from a point A to point B. Do you think this sensor will fit for my needs? It seems all accelerometers I have seen so far only measures angular accelerations.

what about the ADXL345 board , is it the same setting ? is there any data sheet for this

Hello, first of all great video! I have bouth this same accelerometer yesterday and was abble to make the circuit and type the program thanks to your video. But i have the problem that i do not receive any data from it. My X Y Z axis stay at zero, do you have an idea what is cosing this? Thanks,

can u explain more why you used 16 and 8 for 0x2D?

why do you need to pull up both i2c connections? also, does it matter what resistor is used?

hey mr. how can we write 16 to toggel d3 & write 8 to go into sleep mode. it dsnt make any sense plz could u explin this ??also the output

what are the units of the values ? and the maximum range of values, in order to convert it to N/m ?

Hello! Can this Arduino with Accelerometer readings(output) be read in the Labview wave form program? Thanks!!

Write(16) is D4 not D3, Write(8) is D3, not sleep. The x,y,z calcs convert 2 8 bit bytes to a 16 bit word also btw.

Hy EEEnthusiast! I have a bike (motorcycle) and I love doing wheelies. The thing is that at night the headlight lights up into the air and might not be seen by upcoming traffic. I thought that I can fit some COB lights underneath the bike and in any various places that will have a strobe effect and that they turn on every time the bike goes up in the air :D I bought a Digispark and this gyroscope trying to start this project, but I don't know anything about codes whatsoever. At the end of the video you are saying that if we have any questions, we shoulf post them. So my question is: are going to help me fulfill this awesome job that it will end up? :D Thank you master!

Why do you need the 20k pullup resistors on SDA and SCL? I thought they are allready pulled-up by 4.7k resistors that are surface mounted on the board. Checking other videos using this module they don't hook up any pullup resistors the way you do it

@basedonprinciple

Depending on the breakout board some of them have the pull-up resistors and others don't (for example the sparkfun ADXL345 doesn't have the pull-ups, whereas I think the Adafruit does.)

So, I want my robot to make controlled turns ( i.e turn to a specific angle and stop). What should I use acclerometer or gyroscope? Until now, I assumed gyro, but seeing this tut, I observed that the accelerometer is showing the angles w.r.t the axis ( i think it was that ) and wondered if this is what i need?

@jeffreydijkstra3391

with the accelero you can measure gravity's G force, so you can measure the angle its standing at.

Have used 3 axis gyro

Im only recieving positive values? Any clue why? If the raw data goes below 0, it jumps to 65000, but that would be 16 bits? However the resolution is 12bits maximum

could you use the accelerometer without the arduino ?

Hey, I'm not sure what's exactly happening in it, the program seems to be working exactly fine but there is one part that's still confusing me, " xyzregister=50" here you gave a "0000000000110010" into the xyz register, then how come the sensor is outputting values for all the three axis?
