Add new sensors and actuators using just a raspberry


I need help for a project. I need to assort block by their coulor. The task is
to do this with an raspberry using cayenne, if possible without an arduino board.
Is it possible to add a colour sensor? And a servo motor? I just can find three or four sensors.

Thanks in advance for your help-.

yes it is possible to add a color sensor and sevro motor with cayenne on raspberry pi. do you have any docs for the color sensor you are using?

what do you mean by this?

Hi. I dont have one yet. But I was just wondering why these devices arent in the list.
Do I have to add an Arduino?
Or do I have to add a device to convert analog to digital signals?

if you are using a raspberry pi then you can connect the sensor and send to cayenne using this GitHub - myDevicesIoT/Cayenne-MQTT-Python: Python Library for Cayenne MQTT API
