Problem in Interfacing PMODIA AD5933 board with ARDUINO UNO

[suraj.mallik]

I am facing problem in interfacing the  PMODIA AD5933 board with ARDUINO UNO.

I am using the attached Library and Program to find out the impedence, phase and frequency measurement.

It is running if the start frequency is set to 1000 Hz in the program. The problem is I'm calibrating with RFB = 100K and Rcal = 100K but the impedance is coming in negative value.

PMODIA AD5933 Board Connection with ArduinoUNO Board is : 

SDA--> A4

SCL--> A5

VCC--> 3.3V/5V

GND-->GND

Hi @suraj.mallik,

Unfortunately, we have not used that particular library that you linked to so I do not have any immediate advice for that. What I can recommend is that you look at this thread for some additional information using the Pmod IA.

Let me know if you have any questions about this.

Thanks,
