How to Build Electronics Projects With the ESP8266 and esp32 Microcontrollers

Learn how to build practical electronics projects with the powerful ESP8266 and esp32 microcontrollers. Discover how easy it is to access information over the Internet, update web pages and create mobile apps that include speech recognition or GPS route tracking.

A smart shopping cart is designed with NodeMCU & RFID to make the billing process easier. A motion sensor is used to detect movement & display it on the webpage including date & time.

Family Robot

The Family Robot is a simple remote-controlled robot that can recognize voice commands. It can also track movement and other information to keep an eye on your kids while they play. You can even use it to control household appliances and other equipment.

This is a project that uses an ESP32 as a wireless access point. The ESP32 creates its own Wi-Fi network, and nearby devices can connect to it. You can then monitor the device through a web server.

This is a project that uses a BME680 sensor & ESP8266 through the BSEC library & Blynk App to check environmental data remotely. The data can be exhibited on the LCD & website including date & time.

UTFPRBot

Founded in 1970, the UTFPR is Brazil’s only engineering university offering 117 undergraduate and 64 graduate courses (including doctorates). The University is also home to applied research laboratories, specialized libraries and teacher education for physics, chemistry, mathematics and language education.

Explore the ESP8266 and ESP32 microcontroller’s powerful Wi-Fi communication, and learn how to update web pages, use Bluetooth Low Energy for mobile device communication, design mobile apps to remotely control devices with voice recognition, incorporate Google Maps in GPS route tracking and generate signals with the timer IC.

RFID-based Database Security System

This RFID-based security access control system combines RFID technology with keypads for identification and database management. This allows efficient management of secure areas, easy edition of user records together with their attributes and prevents unauthorized access to the system.

Off-site data storage is one of the most popular strategies for improving enterprise business continuity. However, outsourcing this process raises important security considerations that are often disregarded or misunderstood by service providers. This paper presents a secure IoT platform that uses the ESP32 microcontroller and its peripherals to protect off-site data from unauthorized access.

Smart Shopping Cart

Metal shopping carts have survived for decades mainly because they’re rugged, cheap to replace, and can be left out in all weather without a lot of damage. But some grocers want to replace them with smart carts that can reduce friction at the checkout and make people shop more.

Several companies have tried to improve the basic shopping cart with technology that allows shoppers to check their total, apply coupons, and identify products on their own. But hesitancy over returns on investment remain. Moreover, some consumers are wary of using self-checkout machines because of past failures and security concerns.

Motion Detector System

Motion sensors are an important part of home security, helping to prevent burglars from breaking into your property. They can also be used to monitor the activities of children and pets.

A motion sensor works by emitting a wave of radiation (microwave or infrared) and receiving movement information based on what bounces back. There are two main types of motion sensors: active and passive.

This project involves using a Wemos D1 mini, a standard PIR motion sensor and open source code to create a simple internet-connected motion detector. When the device detects movement, it triggers IFTTT.

Alert System for Rash Driving

Rash driving is one of the most common reasons for road accidents. To prevent such accidents, an alert system is designed that will send a message to the police whenever rash driving occurs.

The device consists of limit switches which are fitted in front & back of the vehicle. When the accident happens, these switches get pressed and give signal to the microcontroller. The microcontroller then activates the buzzer and immediately sends an SMS to pre saved numbers along with proper location information i.e latitude & longitude of the incident.

Vehicle Accident Alert System

The Vehicle Accident Alert System is an ESP8266 based IoT project that enables to detect and alert the ambulance & police service in case of a car accident. It includes vibration & GPS sensor modules that sends information to the base station via SIM900 GSM module.

The device also has a memory means to store data from the sensor modules for a predetermined time, preferably 30 seconds. Upon detection of an accident, the device automatically sends the information to the base station via SMS and alerts the emergency services.
