Help! My project is to control two motor with nodemcu esp32 and l298n motor driver using Cayenne iot platform, but i dont really know how to set up Cayenne to control two motor and also the coding.

This would be a good place to start https://www.arduino.cc/en/Tutorial/HomePage

Is that any references for coding with motor’s speed control and how do i create a slider on cayenne website that can control it… I mean what is the coding looks like so that i can use slider on cayenne website to control the motor speed

Cayenne Generic PWM Output Example

This sketch shows how to set up a Generic PWM Output with Cayenne.

The CayenneMQTT Library is required to run this sketch. If you have not already done so you can install it from the Arduino IDE Library Manager.

Steps:
1. In the Cayenne Dashboard add a new Generic PWM Output widget.
2. Select a virtual channel number.
3. Select a slider widget.
4. Set the slider widget min value to 0 and max value to 255.
5. Set the VIRTUAL_CHANNEL value below to the virtual channel number you selected.
6. Attach an output device to a digital PWM pin (3, 5, 6, 9, 10, and 11 on most Arduino boards).
7. Set the ACTUATOR_PIN value below to the digital PWM pin number you selected.
8. Set the Cayenne authentication info to match the authentication info from the Dashboard.
9. Compile and upload this sketch.
10. Once the Arduino connects to the Dashboard you can use the slider to change PWM values.

Does this coding can work together with l298n motor driver?

the above code is for receiving the data from the cayenne dashboard. then you need to add the L298n code to work.
