DHT12 Sensor Interfacing with Linkit Smart 7688 Duo using Python/Arduino

April 27, 2020June 8, 2021 Bikash Narayan Panda

I got the Linkit 7688 Duo couple of years back but was not able to work on it apart from getting started and programming the onboard Atmega(w/ Arduino Bootloader) using Arduino IDE video. But recently I thought of checking out the python programming aspect of it, as the MPU runs an OpenWRT based lightweight OS over which we can run any programming language as long as the limited resources available on the board are sufficient. The board comes with one MPU (MT7688) and one MCU(Atmega32U4) I am working on a…

Automatic project structure/git creation in Windows

January 27, 2019April 3, 2020 Bikash Narayan Panda

While working in projects on a daily basis, as I do for YouTube videos, we tend to create the same folder structure and related repositories every time, as we move to the next project. For me, it is like creating folders for video, code, uploaded video, schematics and so on and in my most of the video for YouTube, I always create almost same folders. Along with that, I create GitHub repository to host the codes that I use in the project or tutorial to distribute. And I hate doing the…

Connected Weighing scale using HX711 and ESP8266

January 20, 2019

Since I got into Home Automation System, I have always wanted a central system with as much as information about me starting from my food habit to each and everything that can be measured or collected. You can say that it is greatly influenced by JARVIS of Iron Man which came around my Engineering days. Coming to the topic, I recently managed to connect a regular bathroom weighing scale to my Home Automation System (OpenHAB) using MQTT. So basically this post is all about how to do that. For the weighing…

ESP32 LoRaWAN Node using Arduino

December 31, 2018January 4, 2019 Bikash Narayan Panda

To test out the recent addition in my lab that is the LoRa gateway, I needed one LoRa node also. LoRa modules are available to be used with Arduino as well as Raspberry Pi and are pretty cheap too. However, you can get complete LoRa module with ESP32 and OLED display at pretty low price from Banggood, and they fit the purpose. And by using these, you don’t need to jumble around jumpers. In this post, I have covered how to make a simple, cheap LoRa node that can send…

Wi-FI Remote for MI TV using ESP8266

November 15, 2018November 15, 2018 Bikash Narayan Panda

I got an MI Smart TV and was pretty much interested in including that in my Home Automation system (OpenHAB). It is supposed to be controlled so that it can be turned on or off based on profile and scene. Although the TV does support MI TV remote over Wi-Fi, it is not able to turn on the TV when it is off. The easiest way to do so is to replicate the remote to an ESP8266 board is having an IR LED and Wi-Fi. By using it everything that…

PIR Sensor with Arduino

October 5, 2018

PIR sensors are really simple and easy to use as well as cheap motion detection sensor. The feature that it is easy to interface with any microcontroller makes it widely usable. This post is a simple one around how to interface any PIR sensor having digital output to the arduino board. There are many kinds of PIR sensors available having stuff like onboard relay etc. but the one I am using gives digital output whenever it detects motion. Due to that, it is easy to interface with any microcontroller. …

Cheap LoRa Gateway using Pi & RAK831

September 23, 2018September 23, 2018 Bikash Narayan Panda

Lately, I have been working with LoRAWAN and I don’t have Lora gateway around. As you might be knowing LoRAWAN network requires a gateway to push data to the internet. As Lora is not an IP based protocol the gateway helps it in doing so. Basically, multiple LoRAWAN nodes transmit data to the gateway and the gateway transfers the concentrated data to server backend. Server backend which resides in the cloud contains a network server which helps in managing the network and the application server which is responsible for the data and…

RPi GPIO Programming using Arduino Web IDE

August 12, 2018October 3, 2018 Bikash Narayan Panda

Recently Arduino has launched support for programming ARM-based SBCs by using the Arduino web editor and Raspberry Pi is one of the SBCs in the list. This video is all about the basic setup to get started with the programming of the Raspberry Pi GPIOs by using Arduino codes. The setup is pretty simple and will help you if you are more comfortable in the Arduino ecosystem as compared to python. More depth functionalities are yet to be checked.

Arduino: String to Array Conversion based on delimiter

July 20, 2018March 31, 2020 Bikash Narayan Panda

This is a simple sketch on how to convert any String to Array in Arduino based on any token or delimiter. Whenever you are working on any project which involves data transfer between Arduino and Other devices/micro-controllers using serial or Wi-Fi or Ethernet you might need to transfer chunks of data and usually the data are not mapped unless you are using JSON or XML. Use of JSON and XML works fine, but proper parser needs to be added to the micro-controller to parse the encoded data. So if required…

OpenHAB2 Installation on Ubuntu Server (16.04)

May 29, 2018May 29, 2018 Bikash Narayan Panda

In my last post about the installation of Zulu JDK to Ubuntu 16.04 server, I covered how to do so and was required so that OpenHAB can run on my server. This post is in the line of my last post and is about the installation of OpenHAB to ubuntu 16.04 server. This post is all about installing OpenHAB to Ubuntu 16.04 using the manual method. I tried with apt-get, but that didn’t work for me. STEP 1 (Download OpenHAB runtime): Navigate to a folder where you can download files…
