Firmata protocol with Raspberry Pi and Arduino

Firmata with Arduino and Raspberry Pi

Firmata is a protocol that is used to communicate with microcontrollers from any tablet/pc over the serial interface. There are implementations of this for other platforms too along with Arduino. You can find support for this if you are using any Arduino IDE released after 2008.Use of this protocol lets you access GPIO of Arduino from any host device natively without uploading the sketch each time you change the sketch. You can use Arduino as ADC for your Pi as it doesn’t have native ADC pins, you can also interface…

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…
