Smart Blind Stick using Arduino

This Smart stick will have an Ultrasonic sensor to sense distance from any obstacle, LDR to sense lighting conditions and a RF remote using which the blind man could remotely locate his stick. All the feedbacks will be given to the blind man through a Buzzer. Of course you can use a vibrator motor in place of Buzzer and advance a lot more using your creativity.

Automatic AC Temperature Controller using Arduino, DHT11 and IR Blaster

In this project we are going to make a small Automatic Temperature Control Circuit that could minimize the electricity chargers by varying the AC temperature automatically based on the Rooms temperature. By varying the set temperature periodically we can avoid making the AC to work for lower temperature values for a long time and thus making it consume less power.

Fingerprint Based Biometric Voting Machine

We all are quite familiar with Electronic Voting Machines, where your vote gets registered electronically and you don’t need to use ballot paper to vote in election. Today security is a major concern and it also needs to be ensured that someone can’t vote twice, so this problem can be solved by introducing Finger Print Based Voting, where a person can be authorized based on his finger Print. This will also stops fake voting.

LED Strobe Light Circuit  

In this project let us develop an LED Strobe light circuit using the popular 555 timer IC. A strobe light or a stroboscopic lamp is one which can produce regular flashes of light. We are designing this circuit using a 555 timer for setting the delay between each flash and a high power LED light as the source of light. At the end of this project we will learn how to use 555 timers in monostable mode and how to calculate the delay for such a circuit.

Smoke Detector Circuit

This smoke detector  circuit triggers the Buzzer whenever it detects Smoke or fire near by it. This circuit mainly uses MQ6 Smoke/Gas sensor to detect the level of smoke

Interfacing OLED with Arduino

The term OLED stands for “Organic Light emitting diode” it uses the same technology that is used in most of our televisions but has fewer pixels compared to them.  It is real fun to have these cool looking display modules to be interfaced with the Arduino since it will make our projects look cool. We have covered a full Article on OLED displays and its types here.

High/Low Voltage Protector Circuit

This 

High and Low Voltage Protection Circuit will cut off the power supply to the appliances in case of High or Low voltage. It will also show a alert message on 16×2 LCD. In this project, we have used PIC Microcontroller to read and compare the input voltage to the reference voltage and take the action accordingly.

IOT based Security System with Voice Message Using ESP8266

This is another interesting IOT project in which we will build a Security system which can trigger an E-mail when it detects someone. This project has blend in the power of ESP8266, PIR sensor and ISD1820 Voice module. At the end of this article you would have built a fully functional Security system which can be Armed/Disarmed (Activated/De-activated) remotely via internet. You can record your own audio clip which will be played when a movement is detected and also send a mail with Date and time to a particular E-mail ID stating the intrusion. Cool enough…..!!!??

IoT Junction box for Home Automation using ESP8266

In this project let us learn how to make a Junction Box whose switches can be toggled remotely using your Phone or Computer with active internet connection.   This project is capable of toggling any two AC loads whose current rating is not more than 5A or ~800Watts.  Once you understand the concept you can extend the number or AC loads by using advanced ESP modules and also increase the power rating of the loads by using high rating relays.

Virtual Reality Project using Arduino and Processing

This is a very interesting project in which we are going to learn how to implement virtual reality using Arduino and Processing. For most of us, the movie Iron man by Jon Favreau has always been an inspiration to build new things that will make our life easy and more fun. I have personally admired the Techs that are shown in the movie and have always wanted to build something similar to that. So, in this project I have tried to mimic the Virtual reality stuffs that happen in the movie, like we can simply wave our hand in front of the computer and move the pointer to the desired location and perform some tasks.
