Bouncing ADXL335 values

Development Boards Arduino

Hello Everyone

I wanted to ask about a strange appearance. I just received the ADXL335 and connected it to an Arduino UNO. I used powering by connecting it to the Analog IN pins aswell as 3.3V and GND from the power pins of the Arduino. But thats not the problem i suppose. My Problem is that i get weird values for x,y,z. The values seem to loop from 0 up again and again. Does anybody know about this or a similar problem?

Thanks for the support.

Best regards

Me again…

Sorry for the stupid question, but i might found the problem. It could be that i did not properly wire the parts. I will test it again after having assembled all properly with some help. I have to admit that im not very used to assemble electronics.

Thanks anyway…

3.3V and ground to power to ADXL335.

Instead of connecting the X, y & z analog outputs to the Arduino, measure these with a Voltmeter (black connected to the ADXL355’s ground). This way any Arduino code issues are not involved.

Let us know what values (Voltage) you get on each ADXL355 output.

Thanks for the support.
