Abstract

TM1638plus is an open-source Internet of Things (IoT) project. An Arduino library to drive TM1638, TM1637 & MAX7219 seven segment modules. An Arduino library to display data on a 8-digit TM1638 seven segment module's. This library supports all 3 of the known models on market. It is built using C++, Arduino. The complete source code is publicly available on GitHub under the GNU General Public License v3.0, making it a useful reference for students building an Internet of Things (IoT) mini project or final-year project.

1. Introduction

An Arduino library to display data on a 8-digit TM1638 seven segment module's. This library supports all 3 of the known models on market. see Documentation section below. As of version 2.2.0 the library also supports TM1637 & MAX7219 seven segment module's.

2. Objective

An Arduino library to drive TM1638, TM1637 & MAX7219 seven segment modules.

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

4. Technology Stack

C++Arduino

5. System Requirements

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

  • Arduino IDE / PlatformIO or a C++ compiler (g++)
  • Target board (e.g. Arduino, ESP32) where applicable
  • Git (to clone the repository)

6. Installation & Setup

git clone https://github.com/gavinlyonsrepo/TM1638plus.git
cd TM1638plus

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?
