In this masterclass, Ably’s Developer Advocate, Srushtika Neelakantam, will walk you through the basics of IoT and the realtime communication protocol these devices like to use i.e. MQTT.
She’ll then show you how to build a realtime attendance logger from scratch that:

• Detects the use of an entry keycard
• Publishes this info in realtime to an Ably channel
• Ably in turn pings Zapier
• Zapier in turn publishes this info to a Slack channel all in a matter of milliseconds.
