Question/Issue:“I have trained a model that runs on an ESP32-CAM. I want to add two servos to the program so that when objects are recognized, they perform certain movements. I am confused about which part of the code to use.”

**Project ID:**object detection

Hi @tepes,

After calling run_classifier(), your inference results will be stored in an ei_impulse_result_classification_t struct (you can read the API docs for that struct here). From there, you need to access the classification values and find the maximum value to determine the class. See this code example for how to access the classification values.

For example, if your ei_impulse_result_classification_t is named result, then you can do something like the following (assuming class 0 is “idle” and class 1 is “my_movement”):

if result.classification[1].value >= 0.5 {
  // Do servo movement
}

Hope that helps!

Hi @kentvillamor05
Refer to this answer by @shawn_edgeimpulse. This is another option that could work for your project as you mention in your post Nano 33 BLE with OV7670 and SG90 Micro-servo motor

Let me know if it it works for you.
