Project Description

This was a research project I undertook to better understand MQTT broker-client relationships. I am working on a project that utilizes this secure messaging system for the internet of things.

I created a Raspberry Pi remote controlled robot using Youtube tutorials made by John Gallaugher. You can find this totorial here

This series of videos required me to purchase all the hardware. This included a Raspberry Pi 4, the Wave Share motor driver HAT, the mini round chassis kit, and various other cables and components. The robot takes Python commands via Circuit Python. These are transmitted from a mobile app interface (made on Xcode) that acts as an MQTT client. I used the Mosquitto MQTT broker to receive the topic messages.

This project gave me a more solidified understanding of MQTT broker to client messaging and was fun to work on.
