Arduino Uno + Ethernet Shield 2 + Lobot Arduino Uno Sensor Shield

Hi All,

I m new to this Space. I m working on a Project to connect LeArm Robotic Arm via Ethernet Shield 2.

As a first step i connected Arduino uno board with Serial port and i am able to control Robotic Arm Servos.

As a next step i tried to control Robots over Network.

I have attached My Ethernet Shield 2 w5500 over Arduino Uno and I m able to get IP address of Arduino.

But if i mount Extra sensor (Lobot Arduino Servo Controller) over Ethernet Shield 2. I m not able to get the IP of my Ethernet Shield.

It prints 0.0.0.0

If i remove Lobot Sensor from Ethernet Shield i m able to get the IP.

Please Let me know how to solve this issue.

Thanks

did you check the information about pins used by the shields?
Ethernet shield without SD card inserted uses on Uno pins 10,11,12,13. with SD card pin 4 is used too

There is no SD card on shields...

This how the set up

Ardiuno uno - Ethernet Shield

I'm able to receive IP of Ethernet Shield

Ardiuno Uno - Ethernet Shield - Lobot Ardiuno Servo Sensor shield

I'm not able to receive IP of Ethernet Shield

Ardiuno Uno - Ethernet Shield - Lobot Ardiuno Servo Sensor shield

don't use or initialize the pins required by the Ethernet shield for the servo shield
