Hello. I downloaded the **pico-v1.25.0-pimoroni-micropython.uf2** file to control the legs of my hexapod robot, and I connected it using Thonny. However, I’m getting an error saying that the **servo2040** library cannot be found. I’m not sure what is causing this problem.

Here is my environment:

- **OS:** Linux

- **Hardware:** Raspberry Pi 5

- I am writing and running the code through Thonny on the Raspberry Pi.

Additionally, when I connect the Servo 2040 board, the motors do not show the expected rainbow-colored LED effect.

There is another issue: I followed the exact hardware setup from the YouTuber **“Make Your Pet,”** and the Android-based pre-made app is able to control the robot successfully. But when I try to control the motors through **my own code using Servo 2040** , it does not connect at all — which is the main problem I’m trying to solve.

Typo in line 2 maybe? the error message is saying “no module named servo **i** ”

Looks like you had an error in the import code.

> from servo import Servo, servo2040
> 
> #Create a servo on pin 0
> 
> s = Servo(servo2040.SERVO\_1)
> 
> #Enable the servo (this puts it at the middle)
> 
> s.enable()  
> time.sleep(2)
