         Bluetooth Controlled Toy Car using Arduino After developing few popular  robotic projects  like  line follower robot ,  edge avoiding robot ,  DTMF robot ,  gesture controlled robot , etc. in this project we are going to develop a  bluetooth controlled robo car . Here we used a Bluetooth module to control the car, and it is also an android based application. www.circuitsindia.blogspot.com Components Arduino UNO DC Motors Bluetooth module HC-05 Motor Driver L293D 9 Volt Battery and 6 volt battery Battery Connector Toy Car Bluetooth controlled car  is controlled by using Android mobile phone instead of any other method like buttons, gesture etc. Here only needs to touch button in android phone to control the car in forward, backwardd, left and right directions. So here android phone is used as transmitting device and Bluetooth module placed in car is used as receiver. Android phone will transmit command using its in-built Bluetooth to car so that it c

DRAWING CAR ARDUINO For a project at school I had to make "digital street art". One of the requirements was using arduino. I made a small car that draws the sound levels as it moves along. www.circuitsindia.blogspot.com                           STEP 1: APPARATUS REQUIRED what you will need for the basics is: Arduino Uno Rev3 Arduino Motor Shield Rev3 2x 9V battery ADAFRUIT: Electret Microphone Amplifier - MAX9814 with Auto Gain Control 2x Drive Motors (Drive with 3-6vdc, 200-400 mA run, 1.5A hard stall) Jumper wires Parallax standard Servo 2x 9V battery clip with 5.5mm / 2.1mm plug mountig platform I bought a smart car kit and used the drive motors, wheels and the mounting platform from it. what you will need for finishing off chalk 2x pingpong Ball balsa wood 8mm Foam board 5mm a long the process I will give some codes for testing each individual part. At the End I will post the finished code that you wil need to make it work. In this

Audio Transfer using Li-Fi Technology With the boom of Smart Phones,  Internet of things  (IoT), Industrial Automations, Smart  Home Automation systems  etc. the demand for internet is also growing exponentially. The technology has evolved so much that everything from our car to our refrigerator needs a connection to the internet. This raises other questions like; Will there be enough bandwidth for all these devices? Will these data be secure? Will the existing system be fast enough for all these data? Will there be too much conjunction on network traffic? All these questions will be tackled by this upcoming technology called  Li-Fi . So  what is LiFi ?  The term Li-Fi stands for “ Light Fidelity ”. This is believed to be the next generation of internet, where Light will be used as a medium to transport data. Yes you read it right; it is the same Light that you use in your homes and offices which, with some modifications can be used to transmit data to all your devices that r

Home Automation Using Google Assistant This includes creating Adafruit account then linking to IFTTT website then adding to Google Assistant for voice commands. Story The idea behind this is to control home devices with voice. On the market there are many devices available to do that. But making your own is awesome. So, let's do it. Build your personal assistant that will do the work for you. Just your assistant requires voice commands. Part 1 Setting  Adafruit.io Part 2 Setting IFTTT account and linking with Google Assistant app: Part 3 Code #include <SoftwareSerial.h>// import the serial library SoftwareSerial mySerial ( 2 , 3 ); // RX, TX int Data ; // the data receive d from the app store here int a = 0 , b = 0 , c = 0 , d = 0 , e = 0 ; //used for key presbs or not int ONE = 5 ; //Digital pin 6 isS used to ON relay 1 int TWO = 6 ; //Digital pin 7 is used to ON relay 2 void setup () {
