Here are photographs of each accelerometer breakout board which we created to make these small chips easier to use:. The primary difference between the two is the range of acceleration they measure.
In this tutorial, we will help you learn how to use these accelerometers so you can quickly and painlessly integrate them into your project[s].
What is the difference between adxl 335 and 337
Here is what we'll cover:. You may also need a breadboardjumper wiresand straight male headers to follow the example setup, if you don't already have these or another way of connecting the Arduino to the breakout board. Before continuing on with this tutorial, we recommend you be somewhat familiar with the concepts in these tutorials:.
As you can see, each breakout has the same pins broken out. Here is some information about each pin:. You can use a 5V or 3.
Be aware though, that your analog to digital ADC readings will vary depending on whether you're using a 5V or 3. Both will work, just be aware of how it affects the numeric values the microcontroller reads. Fortunately, you don't need a lot of power to make the accelerometers work. However, if the X pin reads 3. The usage of both chips is essentially the same, but interpreting the readings is different due to the scale that each chip measures. The ADXL also has 4 mounting holes, as opposed to just two, to allow for a more secure physical connection to your project since it will likely be subjected to more extreme force.
Also, for both chips, 0. This means the maximum rate you can collect acceleration data from the IC's is Hz. Before you can plug your accelerometer breakout board into a breadboard and connect it to anything, you'll need to solder connectors or wires to the breakout pins.It can measure the static acceleration of gravity in tilt-sensing applications, as well as dynamic acceleration resulting from motion, shock, or vibration.
ADXL is 3v3 compatible device, it's powered by a 3. It has three outputs for each axis i. These are analog outputs and thus require an ADC in a micro-controller. Arduino solves this problem. We will be using the analog functions of Arduino. Did you use this instructable in your classroom? Add a Teacher Note to share how you incorporated it into your lesson. We will be displaying two different values for one analog value read.
The first value is the ADC converted value in bit resolution 0 to while the second one is mapped for PWM and it is in 8-bit resolution 0 to Question 1 year ago on Step 4. Question 1 year ago. Hello, is there a reason you are mapping the 10bit analog input to an 8 bit value 0 ? What can I use the converted value for that is not possible with the 10 but value? I am really need to this and dont understand why the conversion is made and over all how to use it in other projects as well.
Please help me. I am using ArduinoDroud to write the above given code but it shows error when I vompile it. Can u please help me out. I am doing a project which involves using the speed of a motor so how do I find the acceleration of the motor using ADXL Reply 3 years ago.
Hey, You'll have to refer the datasheet for MPU sensor. Plz help. I have a accel. I also connected st to 3v3. My kit works fine, would my accel. By apoorveinstein Follow. More by the author:. About: An electronics enthusiast Add Teacher Note.
Use 2-pin relimate for connecting Vcc and GND.There are 6 pins: — 3. There are some things to note: If you use the ADXL breakout board the way described here, you have to set the Arduino to an internal voltage of 3.
Connecting the ADXL337 to the Arduino
This is possible with many Arduino boards. In this way everything works correct and you get the best resolution of the AD conversion of the Arduino. Electronics and measurement: The accelerometer works as a resistor whose resistance is relative to the acceleration of the respective pin and axis. This means the standard voltage is 1. If you take a multimeter to measure the pins x,y and z you should get the value 1.
On the z axis you should get 1. This is because the earth acceleration respectively the gravity is acting on the ADXL in the z axis. As you can deduce from the values 1 g corresponds to mV see specsheet.
So how to calculate? The problem is the Arduino is working digital. Because of that every value at one of the analog pins is converted from analog to digital. The internal reference voltage is usually 5v, but as described above I changed the internal voltage to 3.

Just adapt to the values of your ADXL and everthing is fine. Result and error checking of values: If you print the output of the serial interface with e. The logic is simple. And this means that values higher than the usual y value and values lower than the usual y value must 0 sum for a non-moving vehicle. Submit Comment. Spamcheck Enabled.

They all got a tiny device called Accelerometer built into the circuitry which can sense when you tilt it from side to side.
The brilliant scientist Isaac Newton in his second law of motion defined acceleration by relating it to mass and force.
In other words, acceleration is the amount of force we need to move each unit of mass. Suppose, the cube is in outer-space where everything is in weightless state, the ball will simply float in the middle of the cube. If we suddenly move the box to the left with acceleration 1g A single G-force 1g is equivalent to gravitational acceleration 9.
If we measure the force that the ball applies to the wall X, we can get an output value of 1g on the X axis. The ball will simply fall on the wall Z and will apply a force of 1g, as shown in the picture below:. This is because the gravitational force is pulling the ball down with force 1g. The accelerometer measures the static acceleration of gravity in tilt-sensing applications as well as dynamic acceleration resulting from motion, shock, or vibration. This structure is suspended by polysilicon springs.
It allows the structure to deflect at the time when the acceleration is applied on the particular axis. Due to deflection the capacitance between fixed plates and plates attached to the suspended structure is changed. This change in capacitance is proportional to the acceleration on that axis. It can measure the static acceleration due to gravity in tilt-sensing applications, as well as dynamic acceleration resulting from motion, shock, or vibration.
The sensor works on power between 1. However, an on-board 3.
This breadboard friendly board breaks out every pin of the ADXL to a 6-pin, 0. This includes 3 analog outputs for X, Y and Z axis measurements, 2 supply pins and a self-test pin which allows you to check the functioning of the sensor in the final application.
The analog outputs are Ratiometricmeaning 0g measurement output is nominally equal to half of the 3. VCC pin provides power for the accelerometer which can be connected to 5V on the Arduino. X-Out pin outputs analog voltage proportional to acceleration exerted on X axis. Y-Out pin outputs analog voltage proportional to acceleration exerted on Y axis.
Z-Out pin outputs analog voltage proportional to acceleration exerted on Z axis.Log in. Site Search Log in. Accelerometer Unit Forcing Cell. Access to accelerometer's raw data. ADIS orientation.
