• Close the arduino IDE. otherwise you won't be able to communicate with the serial port from the node script.
• Run the app.js script node app.js
• Use ngrok to expose your local server to the world. Create a static ngrok domain so that you can use the same url every time - https://ngrok.com/blog-post/free-static-domains-ngrok-users
• Run the command with the domain flag ngrok http 3000 --domain=your-domain-name.ngrok-free.app
• In your Twilio account set the webook url for receiving sms to be your static domain /sms - your-domain-name.ngrok-free.app/sms
