ProCodeCG Kids Coding Camp – IoT Programming – Day #3 – 24 June 2017


IoT Programming Coding Camp Day #3 🙂

Today we connect to a MQTT server to be able to publish and subscribe to a topic so we can control our ESPectro remotely via cloud 🙂

We connected to a MQTT server running on one of the computer of the class and also connected to an online MQTT server 😉

We can control the ESPectro via mobile too 🙂



The lessons today required hard work and patience 🙂
