I have downloaded and unzipped the MQTT files and saved in Arduino library files as async_mqtt_client but when I verify the sample code for the project I get error “Program Files (x86) \Arduino\libraries\src/AsyncMqttClient.hpp:3:22: fatal error: functional : No such file or directory

Hello David, I hope you are doing well. That error means that you didn’t install the libraries in the right place or there’s an extra folder that was created while unzipping. Make sure you go to, you Arduino IDE file path and find the AsyncMqttClient library…
Thanks for your patience. Regards,
Rui
