When I go to add actuator and choose Generic and the PWM output then when i head to select the connectivity option then a red ban icon appears on the place where i had to make a selection.
Why so ?
Please help me.

I go to terminal of raspberry pi and run the commands but it is not working
you should be able to see some green widget on your cayenne dashboard when you restart the service. Add them by clicking on the + .

i mean on the device overview dashboard where all the widgets are present. You will need to restart it again while keeping the device dashboard open.

Have you connected your pca to your raspberry pi?
yes
on your pi terminal, restart the service again and share the log.
cd /etc/myDevices/plugins
tail -f /var/log/myDevices/cayenne.log

Looking to drive a servo motor (0 to 180 degrees) using a slider control. Can anyone share a tutorial on how to do this so that I can do it easy?
there are two ways to do this:
- Add a pca9685 plugin to your cayenne pi agent and then modify the plugin code to work with servo motor.
- Use adafruit servo example code Adafruit_Python_PCA9685/simpletest.py at master · adafruit/Adafruit_Python_PCA9685 · GitHub and add the cayenne python example code Cayenne-MQTT-Python/examples at master · myDevicesIoT/Cayenne-MQTT-Python · GitHub. this is much easier as just combine the two examples.
