ESP32 Testing and Debugging Demos

A lightweight ELM327 emulator running on ESP32 over Bluetooth Low Energy (BLE). Supports basic OBD-II commands, provides real-time CAN/ASCII data, and logs both HEX and ASCII for debugging. Ideal for testing OBD-II apps and learning automotive communication protocols.

ESP32-based UART to MQTT (TLS) bridge for remote serial logging, debugging, and long-duration testing.

A simple testing sketch for TFT displays using ESP32. Verifies display initialization, color rendering, text, shapes, and refresh performance. Useful for debugging and hardware validation.

Reads an analog voltage on the Arduino Nano ESP32 and logs the values to an SD card while also printing them over Serial for quick testing and debugging.

Developed and programmed an ESP32-based system using Arduino IDE. Integrated sensors, power modules, and electronic circuits. Designed and assembled the complete hardware system and created a 3D-printed enclosure. Performed testing, debugging, and troubleshooting.

Reads and visualizes real-time IMU data from Arduino or ESP32 via serial port. Displays accelerometer and gyroscope readings in 3D using Matplotlib for quick motion tracking and debugging of robotics or sensor projects. Simple, lightweight, and ideal for testing IMU-based systems.

The ESP32’s UART2 interface is configured in loopback mode, allowing the device to send and receive its own data for testing and validation. The project showcases efficient use of ESP-IDF UART APIs, task scheduling, and real-time debugging through the ESP logging system. It serves as a foundational example for building IoT
