Sorry to ask this kind of question. Is there any good simulator for Raspberry Pi? because I need to learn more about the raspberry pi but my problem that I can't buy all the sensors such as Temperature /Humidity, distance, Navigation, and Motion. Moreover, I need to communicate with another raspberry pi using Mosquitto (MQTT).
I found this : https://docs.microsoft.com/en-us/azure/iot-hub/iot-hub-raspberry-pi-web-simulator-get-started but it seems that it needs the raspberry pi to be connected.
I'm looking for any simulation tools that I can connect wire, put sensors, run the code.
Any suggestion will be appreciated.
Thanks In advance.
