DIY Arduino Smoke Detector

In this DIY project, a Smoke Detector Circuit is designed to sense the smoke in the air and display the same on 16x2 LCD. This circuit triggers the Buzzer when Smoke level becomes higher than 1000 ppm, the threshold value which can be modified in the code. This circuit mainly uses MQ2 Smoke/Gas sensor and Arduino to sense and calculate the level of smoke in air.

Call/Text using SIM900 GSM Module and Arduino

Isn't it to fascinating to create your own cell phone? If you know about working with arduino, its not much difficult, and you can develop interesting arduino projects.  Not that perfect one, but in this DIY project we are going to create basic functionality of a cell phone like making a call/receiving call, sending and receiving text messages. If you are new to GSM module, you can go through this article to understand more about GSM module.

Go through this tutorial to learn about creating basic functionalities of a cell phone by interfacing SIM900 GSM with Arduino.

Private Chat Room using Arduino, nRF24L01 and Processing

How cool it would be if you could communicate with people inside your home or work place without a net pack or Internet Connection?

What if we could customize our chat-screen with our own imaginations?

All this is possible with a microcontroller and a Wireless transmission medium. This Arduino Chat Room using nRF24L01 Project will guide you on setting up a low cost Chat Room in your local area.

Arduino IR Remote Control

I started this project in order to get rid of various remotes at my home and build something single which could incorporate features of all of them. I got this idea when I saw one of my friend’s mobile phone with built in IR blaster, at that time I decided not to buy a similar phone rather make my own device which should be compatible with my existing handset. So here we are going to Convert an Android Phone into an IR Remote using Arduino to control various devices at home.

Arduino LED Scroll Bar

In this post we are covering a detailed DIY project to build an Arduino based LED scroll bar, as shown in the below picture.

This is quite simple project and only requires Arduino nano and few LED stips, along with some other basic electronic components.

So go through the link below to find the circuit diagram, PCB files and a detailed guide to build this beautiful LED scroll bar.

DC to AC Inverter Circuit

Inverters are quite handy in time of power cuts. The most common type of inverter we see in everyday life is UPS (Uninterruptible Power Supply). We use UPS to keep PC (Personal Computer) running in the event of power cuts. UPS keeps up the power delivered until battery bank runs out.

UPS is a system which converts DC to AC. So, UPS takes DC power of battery as input and gives AC power as output. In this tutorial we are going to design a 100 watt 12v DC to 220v AC inverter. This Circuit is easy and you only need few capacitors, resistors, diodes and a transformer. So here the guide and schematics to build this inverter circuit.

Vehicles tracking through GPS is one of the useful technologies. But in this time of IoT where everything could be connected through internet, can we connect the GPS through internet and show data on Google maps? Yes! In this IoT project we are building more advanced version this Vehicle Tracking System in which you can Track your Vehicle on Google Maps. In this project, we will send the location coordinates to the Local Server and you just need to open a ‘webpage’ on your computer or mobile, where you will find a Link to Google Maps with your Vehicles Location Coordinates. When you click on that link, it takes you on Google Maps, showing your vehicles location. Here GPS Module is used to get the location coordinates, Wi-Fi module to send data to computer or mobile over Wi-Fi and Arduino is used to make GPS and Wi-Fi talk to each other.
