Belay

Abstract

1. Introduction

Belay supports wired serial connections (USB) and wireless connections via WebREPL over WiFi.

The Belay Package Manager is for people that want to use public libraries, and get them on-device in an easy, repeatable, dependable manner.

This is lot of work if you just want your computer to do something simple like turn on an LED. Belay simplifies all of this by merging steps 1 and 2 into the same codebase, and manages step 3 for you. Code is automatically synced at the beginning of script execution.

2. Objective

Belay is a python library that enables the rapid development of projects that interact with hardware via a micropython-compatible board.

This project demonstrates how Python, Arduino, ESP32 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?
