Abstract

Tinybasic is an open-source Internet of Things (IoT) project. A BASIC interpreter for Arduino, ESP, RP2040, STM32, Infineon XMC and POSIX with IoT and microcontroller features. Supported platforms right now are all 8bit Arduino AVR systems, LGT8 systems, the various Arduino 32bit systems like the MKR and GIGA. Of cource the RP2040, plain Rasberry PI Pico, ESP8266 and ESP32, Infineon XMC, Seeeduino Xiao and STM32. It is built using C, Arduino, ESP32, ESP8266. The complete source code is publicly available on GitHub under the BSD 3-Clause "New" or "Revised" License, making it a useful reference for students building an Internet of Things (IoT) mini project or final-year project.

1. Introduction

Supported platforms right now are all 8bit Arduino AVR systems, LGT8 systems, the various Arduino 32bit systems like the MKR and GIGA. Of cource the RP2040, plain Rasberry PI Pico, ESP8266 and ESP32, Infineon XMC, Seeeduino Xiao and STM32. A full list of supported platforms can be found here https://github.com/slviajero/tinybasic/wiki/Hardware-Platforms.

My attempt to create a basic interpreter from scratch. The project was inspired by Steve Wozniak's statement that the Apple 1 basic interpreter was the biggest challenge in his professional life. Bill Gates also had started his career and his fortune by writing a basic interpreter for the Altair microcomputer around the same time.

The project has outgrown its beginnings by now. It became a full featured BASIC interpreter with IoT and microcontroller specific features. There is an underlying hardware abstraction layer making the interpreter useable on a number of architectures like Arduino, ESP8266, ESP32, SAMD, RP2040 and various ARMs. Posix and MSDOS.

2. Objective

A BASIC interpreter for Arduino, ESP, RP2040, STM32, Infineon XMC and POSIX with IoT and microcontroller features.

This project demonstrates how C, Arduino, ESP32 can be applied to a real-world Internet of Things (IoT) problem.

5. System Requirements

General requirements for this technology stack — check the README for exact versions.

  • Arduino IDE / PlatformIO or a C compiler (gcc)
  • Target board where applicable
  • Git (to clone the repository)

6. Installation & Setup

git clone https://github.com/slviajero/tinybasic.git
cd tinybasic

Full setup instructions are in the project README.

7. Future Enhancements

Suggested extensions you can add to make this your own project.

  • Add a mobile dashboard using Blynk or Firebase
  • Store readings in a cloud database for history charts
  • Add alerts via SMS / Telegram when thresholds are crossed

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?
