Programming Linkit Smart 7688 DUO using Arduino IDE

Linkit Smart 7688 DUO

In this tutorial, we will see how to program the Atmega324 controller of Linkit Smart 7688 DUO module using the Arduino IDE. The boards come in two flavors, Linkit Smart 7688 and Linkit Smart DUO. The difference between both is that the DUO has an ATMEGA324 controller apart from the main MPU which can be programmed using Arduino. In DUO module GPIOs of both the MPU as well as MCU are exposed and some are even multiplexed. The MCU can also be interfaced or controlled using the MPU but in…

Mongoose OS Installation on ESP8266 and GPIO Access

mongoose OS

This video is around ESP8266 module and how to flash mongoose OS to it.It also demonstrates some basic GPIO programming using javascript.Mongoose OS claims as an Operating System for commercial connected products with features like Security, OTA Updates, Remote Management. As Arduino framework is not reliable to run in production environment its a good alternative with  Arduino compatibility layer that allows using existing Arduino drivers for prototyping. It is both C/C++ ready for production and  JavaScript is for fast prototyping on the target hardware. The JS API calls C API.…

IOT: Power outlet controlled from internet using WeMOS

IOT Based Power Outlet

This is a simple project to make IOT enabled power outlet. This video is around WeMOS and demonstrates how to use WeMOS with thingspeak to control some loads in my home. This project lets you control your devices which you need to connect to the output sockets. As an online server, I have used Thinspeak.com but you can use any server but you just need REST API. Check out the video to get started.

Getting started with Linkit Smart 7688 DUO

Linkit Smart 7688 DUO

In this video, we will see the specs of the module, Configure using the web interface, will access the terminal using SSH. Now coming on to the board this comes is two flavors those are Linkit Smart 7688 and Linkit Smart DUO.Over here what I am having is the DUO module.The difference between both is that the DUO has an ATMEGA324 controller apart from the main MPU which can be programmed using Arduino. Checking out the board on the front side u get 2 Micro USB socket out of which…

IOT With Raspberry Pi using JAVA

IOT_Pi

This post features videos that I published to my YouTube channel in the series “IOT with Raspberry Pi “. This basically contains 4 videos around raspberry pi that show how to use Raspberry Pi as an IOT device. It starts from interfacing sensor to publishing the sensor data to cloud server using protocols like REST or MQTT. For the entire project I have used JAVA and on top of that used various libraries for specific tasks like Pi4J, Unirest, Eclipse PAHO etc (Links provided below). If you have watched any of the videos you…

DHT12 Interfacing with Raspberry Pi using Pi4J

DHT12

This video around raspberry pi showing how to interface DHT12 humidity and temperature sensor with raspberry pi by using JAVA nad Pi4j. DHT12 its a temperature sensor with a 1-Wire and I2C interface to connect with external controllers and having 1-Wire interface makes it compatible with the older DHT11 sensor but with a higher accuracy. For this tutorial, we are going to use the I2C interface of the sensor and to interact with it, we will be using JAVA. One issue with the DHT12 I2C interface is that the device…

Information Display System using WeMOS and MAX7219

MAX2219_Dot matrix

This tutorial is all about making a WiFi-based information display system. This system is built around ESP8266 but not the standalone ESP8266 instead WeMOS is used and programmed using Arduino IDE. So In this video, we will check out how to make an information display system like that using Wemos and MAX7219 based dot matrix display modules. The display system fetches data from the local/online server and displays the received. In this system, u can display any data that you want and that’s up to you however over here I…
