MQTT is your Best Friend

How Internet of Thingsresembles queues for bread rolls?

How you do it when shopping?

Alone in the morning…

There is only one queue…

But later is crowded everywhere!

Queues start to form!

How you do it with TCP/IP?

Fair easy right?

Just use a lib!

But you have 8bit bus, 16Mhz and 32KB RAM

Now do your magic…

Welcome to the world of IoT!
