| One of Pixy2's goals is to be able to easily learn different objects without needing to hook it up to a computer. The button-press teaching method allows you to do this. But for certain objects and/or lighting conditions, the button-press method might need some adjusting. The **Signature teach threshold** setting in the **Expert** tab allows you to adjust how inclusive Pixy2 is when determining which pixels are part of the object during teaching. You can adjust the **Signature teach threshold** while Pixy2 is in teach mode, so you can get "live" feedback while choosing a good threshold. | One of Pixy2's goals is to be able to easily learn different objects without needing to hook it up to a computer.
