Below section covers a list of simple microcontroller projects to learn and work with the concepts of various microcontrollers and architectures. These microcontroller based projects are covered with detailed explanation of working of hardware, circuit diagrams, software and codes.
Microcontrollers are widely used in various industries, electronic products, automobiles etc.. to perform computing or logical operations. With this huge importance the demand of microcontrollers in industries is prominent and hence as electronics engineers it is important for us to learn how to use them. There are a large number of semiconductor companies manufacturing a variety of microcontrollers, the most popularly ones are 8051 microcontrollers, AVR microcontrollers, PIC microcontroller, TI Microcontrollers, Arduino, Raspberry Pi etc.

The Aura AI system is built on a Client-Server architecture that splits the workload between an Edge Device (the physical interface) and a powerful Python Backend (the brain).
1. Firmware (The Edge - aura_firmware.c) The code for the ESP32-S3-BOX-3 is written in C using the ESP-IDF framework. It handles real-time interaction with zero latency.

Human–machine interaction today is heavily centered around speech.
Voice assistants, smart speakers, and voice-controlled home automation systems assume that the user can speak clearly and consistently.
However, this assumption excludes an important group of users:
People with speech impairments Individuals who are temporarily unable to speak Users with…

This project is an IoT-based weather station tailored for farmers to monitor their fields remotely. It collects comprehensive environmental data from Home, including wind speed, wind direction, temperature, humidity, pressure, gas levels, altitude, and rainfall. Using a BME680 sensor and other specialized sensors, all…

Modern smart home systems typically rely on cloud connectivity and internet access, which introduces latency, privacy concerns, and dependency on external infrastructure. In many real-world scenarios, reliable internet connectivity is not always available, and users still require fast, secure, and private home…
Ever wondered if a small, low-cost board like the ESP32-CAM can actually recognise objects or even identify Indian currency notes? In this project, the answer is a clear yes. We combine the ESP32-CAM with the powerful Edge Impulse platform to build a system capable of object detection and image classification right at the edge. By using the Edge Impulse at every step…

Sentio is a project that reimagines the smart home assistant as an interactive digital pet rather than a lifeless tool. While most smart speakers look boring and static, Sentio is an emotive, privacy-focused robot that loves pets and interactions. Crucially, it serves as a central "Guardian" for the home: it integrates a custom Smart Video Doorbell for secure…
