Pharo Things

Abstract

1. Introduction

Now PharoThings is in beta stage together with documentation and videos. It will be improved constantly.

This project is right now on sleeping mode. We do not have the resources to maintain it and evolve it.

2. Objective

Live programming platform for IoT projects based on Pharo

This project demonstrates how Smalltalk, Raspberry Pi, Arduino can be applied to a real-world Internet of Things (IoT) problem.

8. Viva / Review Questions

Common questions examiners ask for projects in this domain.

1. Which microcontroller / board and sensors are used and why?
2. How does the device send data (Wi-Fi, MQTT, HTTP, Bluetooth)?
3. Where is the sensor data stored and visualised?
4. How is power consumption managed?
5. How would you secure the device and its communication?
