Internet control

This sample shows how to control your pumpkin using Azure IoT Central, with lights and a spooky sound.

Set up the speaker and lights as described in the spooky-sounds and single-pixel demos.

You will need an IoT Central app to control the app. You can find out more about how to use IoT Central in the Azure IoT Central documentation

If you don't have an Azure account, sign up:
- If you are a student, you can sign up for Azure for Students. You can also activate Azure for students via the GitHub student developer pack. Azure for students gives you $100 of credit each year you are a student, and you don't need a credit card to sign up.
- If you are not a student, you can sign up for an Azure free account. You will need a credit card for verification, but your card will not be charged. This account gives you $200 of credit for the first 30 days.
