Start making IoT based product: Internet is the virtual world where users are interested in accessing,editing and controlling data.Everyone is eyeing the next big thing in the internet.Now days market booming with the IoT. Internet of Things is the extended form of internet. Real world is connected through virtual world. In an era of electronics based civilization there is always a demand for more better,cheaper and faster electronics devices. These are the key points for the IoT based products development. Main feature of IoT based product is to give remote access of device to the user. Even device which is controllable from Bluetooth is also a IoT device. The end to end form of IoT make that device controllable from any corner of the world. How to step in IoT market ? Product design Flow: Design and Specification finalization: The very first step in product development is to define aspects and specification of product which can not be change through the end of prod...
Bluetooth Controlled Home Equipments: Basic about bluetooth: Bluetooth is a wireless technology standard for exchanging data over short distances (using short-wavelength UHF radio waves in the ISM band from 2.4 to 2.485 GHz) from fixed and mobile devices, and building personal area networks (PANs). Invented by telecom vendor Ericsson in 1994 Radio frequency communication (RFCOMM) The Bluetooth protocol RFCOMM is a simple set of transport protocols, made on top of the L2CAP protocol, providing emulated RS-232 serial ports (up to sixty simultaneous connections to a Bluetooth device at a time). The protocol is based on the ETSI standard TS 07.10. RFCOMM is sometimes called serial port emulation. The Bluetooth serial port profile is based on this protocol. RFCOMM provides a simple reliable data stream to the user, similar to TCP. It is used directly by many telephony related profiles as a carrier for AT commands, as well as being a transport layer for OBEX over Bluetooth. ...
Line follower car : Aim: Create Arduino based Line follower robot from scratch. It is a machine that follows a line, either a black line on white surface or vise-versa. For Beginners it is usually their first robot to play with. In this tutorial, we will teach you to make the line follower robot move on the line with a type of feedback mechanism. It’s the most basic example of adding small intelligence to a robot, but it’s actually the designer’s intelligence!! Requirement: 1) Arduino Uno + Arduino IDE 2) DC geared motors x 2 3) Power bank or 9v or 12v Battery 4) IR sensors (ready made or You can make it by your own) 5) Connecting wires 6) Motor driver ready made or Your own. Working of sensors: IR light is invisible to human eyes it can be detected using IR sensore. As shown in picture below IR LED which is act as Transmitter and Photo Diode act as receiver. When Infrared Light strike on white surface its get reflect back and received by photo diode, while in ot...
ESP 8266 OTA(Over The Air) Update Firmware Demo : My friend Sanket encourage me to do some stuff on ESP8266 OTA. No need of wire to upload Arduino sketch in ESP8266 . OTA give you advantage of uploading sketch or upgrade firmware over the WiFi without any wired connection. *Program uploading is Faster than regular arduino upload. Requirement: 1) Go through previous tutorials of ESP8266 on my blog 2) ESP8266 3) python27 installed on System from where your going to upload firmware.\ Step 1: Download The library and tools required for OTA click here Step 2: Extract downloaded file and install arduino OTA library in Arduino IDE. Step 3: Complile and Upload following sketch in ESP by our regular method through serial terminal . Its necessary to upload first time sketch with OTA suppot. #include < esp8266wifi.h > #include < esp8266mdns .h > #include < wifiudp .h > #include < arduinoota .h > const char* ssid = "WIFI ROUTER N...
ESP8266(Arduino) interface with Firebase: Aim: Make such application in which LED can be control from mobile or website from any remote location where internet connectivity is available. Requirement: 1 ) ESP8266 -E12 WiFi module as shown in picture. You can get start and setup it with help of this post. 2) Download and install firebase-arduino-master library in Arduino IDE. 3) Need gmail account for create Firebase project. Step 1: Go to https://console.firebase.google.com and create new project. Step 2: Click on Database now you will see the host name show in image Copy that host name and past in Arduino code given below at line #define FIREBASE_HOST "fir-app-example.firebaseio.com" Step 3: Go to Setting>Project Setting>SERVICE ACCOUNTS>DATABASE Secretes. Copy "Database Secrets" Shown in below image Copy and paste Database Secrets at the line in code #define FIREBASE_AUTH " example sd2asdasdasdasd2asd3asd2asd2as32...
JHD12864E interfacing with Arduino Uno( 128x64 Bit MAp Graphics LCD) : Requirement : 1 ) JHD12864E LCD 2 ) Arduino 3 ) Connecting wires Aim: Convert and display JPEG image on Graphics LCD as Bitmap image Step 1 : Download and put Glcd library in Documents/Arduino/library folder GLCD library Step 2 : Download BMP-To-LCD software to convert JPEG image to BMP array BMP-TO-LCD Step 3: Make connection of LCD to Arduino UNO as shown in figure. Step 4: Download any image from internet. Step 5: Open image in Paint Step 6: Step7 : Step 8: Step 9: Click on resize without selecting area Step 10: Save image as 1.bmp Step 11 : open Image in BMP-LCD software And click on Genarate code Copy that genarated code in Arduino sketch Step 12: Copy Paste code in bitmaps.h with some mod...
