What kinds of numbers should this thing be putting out? I'm getting stuff in the 700s.

I will note that I ran like 9v through it on accident. When use external reference connected to its VCC pin, I just get zeroes. But when I use internal reference I get numbers in the 700s that do indeed seem to change with my tilt

This is the same width as the Arduino Pro Mini. It would be really amazing if this board were designed so that the holes on one end lined up to A1,A2,A3,VCC,GND holes on one end, and the 2nd, 3rd, or 4th digital pin on the other end, so this could be used as a mini shield.

How do I hook up my wires to the accelerometer? Do I simply loop the copper wire through the holes and twist it back on itself to make the connection?

The graphic on the board showing the orientation of the x,y,z axis is wrong. I didn't notice this at first but when the Y axis failed I noticed that the x axis didn't respond when I rotated the board around Y. A quick check of the ADXL335 data verified that it is the graphic on the board that is incorrect. It should be rotated 90 degrees so that Y points in the direction X does now.

In the wiring diagram, I noticed that the analog pins are wired directly to the board without a logic level converter (for 3.3V to 5V logic level conversion). I'll be using an Arduino Uno (5V), so I think the analog pins are expecting voltages between 0V and 5V (values 0 to 255). If I don't use a level shifter, that means that the input from the ADXL335 will only be between 0V and 3.3V. So does that mean, I need to calibrate the Uno's sketch to expect a max analog pin value of 168? It would seem this would mean reduced granularity of signal. Is that true?

I know some logic level converter (like BOB-12099) are only for use with digital pins, but I'm assuming one exists that supports analog signals. Any suggestions?

I'm doing a project using the ADXL335 accelerometer from SparkFun. The actual project I'm using P5 and it's working great. I'm running workshops in parallel and want to demo the chip in real-time but am currently out of time to build something from scratch. I'm desperate for a simple processing (or something else) sketch that takes my x, y, z values being printed to the serial port from Arduino and visualizes them in some way. Can anyone point me to anything that won't need a lot of coding time and effort just now?

I have a question regarding the provided eagle files.

When I load the .brd file into the free version of Eagle, I'm able to see the top and the bottom layers, but am wondering if this board uses more than two layers? The reason I ask, is because the GND pin is not connected to any of the COM pins of the ADXL335

Thanks!

Hi, how can I figure out to connect correctly this accelerometer from sparkfun with a Flora Atmega32u4? I am new to this kind of hobby but I am pretty sure there must be a way to put them together. I am checking the data sheet of both, but any help would be appreciated =)...

Guys im well new to this whole thing and been racking my brain the last few days how to make my accelorometer make my servo arm spin right 180degrees by snapping it forward a bit. Atm its so touch sensitive my servo is doing all kinds of stuff. Any have any ideas?

I to was curious, how do I connect this to my breadboard simply by looping the wires or is some sort of pin/soldering required? Any help would be great!

linear motion

none

using for keeping a movement horisontally

using and keeping horisontally movement

the accelerator, DDXL335 will be used in one of our scintific experiment at weizmann institute of science, Rehovot Israel. To keep horisontal movement

Is ordered for an experiment task at Weizmann Institute of Science

I used Bildr Example, and as it said, ADXL335 can't have yaw value... But this video below can work! http://www.youtube.com/watch?v=HdApMTRDXes Can anyone kindly show me how to? Thanks a LOT!

Is this accelerometer good for impact sensing?

I'm seeing inconsistent behavior on this model. On 2 separate units, for seemingly no reason, the scaling and offset (volts -> g's) have changed after several days of use. The first unit I did shake fairly hard (more than 3 g's?), but the second unit I was pretty gentle with. Has anyone else seen this behavior?

The cheapest 5V - 3.3V converter on the planet would have to be the red LED. They have a voltage drop of 1.7 volts, so putting a red LED in series with 5V power will let this accelerometer work.

It may be noisier this way for all I know, but it definitely works.

Hi! Does anybody know the mbed code for this accelerometer (ADXL335)? That'd be great! Thanks.

I recently bought this accelerometer but i found that the out put of it on every axis is only about 0.36V or 360mV i have checked with self test pin but it is of no use as there is no change in the output when st pin is connected to vs(3.3V)

if i buy Triple Axis Accelerometer Breakout - ADXL335 .This price $24.95 included the connecter to the computer or not?

if do not included, what connecter using for ADXL335 to connecter to the computer. any link provide for me to buy this connecter

How accurate is this? I need to be able to measure a difference of 0.08 inches in any direction. I know the rule is the lower the measurable g's the more accurate, but how much? I'm going to use this application to place on the end of a gun for dry firing. Any thoughts?

what is the weight of this accelerometer?
I'm looking for the smallest and lightest gyro and accelerometer (digital output or analog) ever in the market (max. 2 gr). I really need it for my MAV.
Is there anybody here can recommend me any with this requirement? Please and thank you...

This is what I was able to accomplish with this board: http://www.youtube.com/watch?v=pN-20mkjZxE.

Slightly noobish question. I'm interested in experimenting with different bandwidths on this chip, which the datasheet says can be selected by placing different capacitances between the x,y,z-outputs and ground. The breakout board comes with 0.1uF capacitors pre-installed, corresponding to a bandwidth of 50Hz. If I wanted to lower the bandwidth, which requires increasing the capacitance, I could just put my own capacitors in parallel with the on-board ones, right? And if I want to increase the bandwidth (lower capacitance), I could put my own capacitors in series with the on-board ones, right? As I understand it, putting capacitors in series will change the overall working voltage of the circuit -- won't this complicate my interpretation of the accelerometer output? i.e., the 0g voltage level, and volt/g response will no longer be as described in the datasheet? Could I damage the chip?

Right out of the package, I stupidly hooked this up to 5V for a minute or so. I switched back to 3.3V, and now all I get are pseudorandom numbers from the device. Did I kill it?

7x7"

Note: The listed dimensions are not correct.

Could someone please give a few examples of typical applications in the +/- 3g range? Thanks!

This is a pretty standard accelerometer. You get all three axis with +/- 3g range. Yes, the silkscreen is wrong for the x and y axis (at least mine was), but who looks at that anyway? The ADXL335 chip is used pretty commonly in other IMU applications due to its simplicity

How do you properly secure this on the chassis/board of the robot?
I'm thinking about ordering one, I have 2 ideas on how to fixate it, but they are both meh.

You guys should either get that wiring example updated, or unlink from it - it shows 5V, when it's a 3.3V device.

I am getting confused.
In the text they say use the voltage between 1,8 and 3,6 VDC.
In the Schematic stand 5 V DC
What to use?

The X axis of my accel just died... just like that... i was reading the voltage values with a multimeter and suddenly X reads 0 V (marked as Y on BOB)
I tried with the self-test pin but it's completely gone... the other 2 axis work fine... has anyone else had this problem??

Does this breakout include the accelerometer? I am new to this stuff and am having trouble understanding all the breakouts and evaluation board nomenclature.
