Intelligent Buggy featuring 4Duino-24

4Duino Intelligent Buggy project demonstrate how does uCAM-II works. This project also utilized two 4duino communicating using Server-Client architecture over TCP. It also uses a buggy car which carry the 4duino server and uCAM-II. By using built-in ESP8266, 4duino client sends a request to 4duino server to move the buggy and capture photo via wireless communication. Server-Client architecture is a network ...

Assistance for Visually Impaired featuring 4Duino-24

Blind Assistance is a project designed to help visually impaired people detecting obstacles in their way. It uses 4Duino, three ultrasonic sensors, one vibration motor and an LED. These components are attached to a walking stick. Blind Assistance alarms the user if there’s an obstacle in his way. These obstacles are detected using an Ultrasonic Sensor. It is able to measure distances from 2cm to 400cm. Ultr ...

Create a Private Chat Room using Arduino, nRF24L01 and Processing

Creating a Local Network to share personnel and confidential data's has become almost impossible for a common man in our modern world. This is mainly because all common chat methods like Whatsapp, Facebook, Hangout and almost everything involves an internet connection. What if, we could share data without the medium of Internet? How cool it would be if you could communicate with people inside your home or w ...

Smart Phone Controlled FM Radio using Arduino and Processing

In this project we will use an existing FM radio which went repair a long time ago, to convert it into a Smart Wireless FM Radio controlled using Phone, with the help of Arduino and Processing. We can convert any manually operated electronic device into a Smart Device using the same procedure.  Every electronic device operates with the help of signals. These signals might be in terms of voltages or currents ...

DIY Speedometer using Arduino and Processing Android App

In this project we make a Cool Speedometer for bikes or any automotives by using Arduino which broadcast the speed using Bluetooth to an Android application that we created using Processing. The complete project is powered by an 18650 Lithium cell and hence highly portable along with your vehicle. To spice it up a bit more I have added the option of charging your mobile phone as it displays your speed. Yes, ...

Virtual Reality using Arduino and Processing

This is a very interesting project in which we are going to learn how to implement virtual reality using Arduino and Processing. For most of us, the movie Iron man by Jon Favreau has always been an inspiration to build new things that will make our life easy and more fun. I have personally admired the Techs that are shown in the movie and have always wanted to build something similar to that. So, in this pr ...

How to Send Data to Web Server using Arduino and SIM900A GPRS/GSM Module

Today we are here with an interesting project in which we will Send Data to the SparkFun server using Arduino and GPRS. This is an IoT based project in which we will use GPRS, present on the GSM Module SIM900A board, to send some data to the web service on the internet. In this project, we will simply enter some text using 4x4 Alphanumeric keypad and send it to SparkFun website using Arduino and GPRS, from ...

How to Get Started with the ESP32

ESP32 is the hottest new wireless chip out there, offering both WiFi and Bluetooth Low Energy radios rolled up with a dual-core 32-bit processor and packed with peripherals of every kind. We got some review sample dev boards, Adafruit and Seeed Studio had them in stock for a while, and AI-Thinker — the company that makes the most popular ESP8266 modules — is starting up full-scale production on October 1st. ...

ESP32 Tutorials

The ESP8266 has become one of those ubiquitous parts that everyone knows. However, the new ESP32 has a lot of great new features, too. If you want to take the ESP32 for a spin, you should check out [Neil Kolban’s] video series about the device. When we say series, we aren’t kidding. At last count, there were nineteen videos. Some are only a few minutes long, but some weigh in at nearly twenty minutes and th ...

ESP32 Hands-On: Awesome Promise

The ESP32 is looking like an amazing chip, not the least for its price point. It combines WiFi and Bluetooth wireless capabilities with two CPU cores and a decent hardware peripheral set. There were modules in the wild for just under seven US dollars before they sold out, and they’re not going to get more expensive over time. Given the crazy success that Espressif had with the ESP8266, expectations are high ...

Arduino Yun SBC adds Wifi and Linux to Leonardo features

[Updated Sep 30] — Arduino announced the first open source Arduino hacker board with built-in WiFi, and also the first to run Linux. The $69 Arduino Yun integrates the functions of an Arduino Leonardo, featuring an Atmel ATmega32U4 microcontroller and 14 GPIO pins, with an Atheros AR9331 WiFi SOC running OpenWRT embedded Linux on a 400MHz MIPS processor. Arduino, the Italian-based project that designs the o ...

Internet Datalogging With Arduino and XBee WiFi

Introduction Are you looking to get your data gathering project hooked into the “Internet-of-Things”? Then check out data.sparkfun.com! It makes posting data to the web as easy as constructing a URL and POSTing it to a server. I wanted to create a quick project to test out SparkFun’s data logging service. Combining an Arduino, XBee WiFi module, and a variety of gas, temperature, and light sensors I built an ...
