Ah not to worry we can make it a web service and host it on the cloud and of course you wouldn't want to run without a authentication so you'd need that and also a database and what if you want to blink the led securely so you'll need to use a homorphic database which is very computationally expensive so just need a couple of VMs and anyway you should start with https://www.npmjs.com/package/blinking and go from there.
