In this tutorial you will get to know that how you can control as many servo motors as much you want with ARDUINO   AND PCA9685. Material requirements are given below :- PCA9685 SERVO DRIVER ARDUINO SERVO MOTORS BRAEDBOARD JUMPER WIRES CONNECTIONS ARDUINO GND          =       GND  of PCA9685 5V              =     VCC of PCA9685 A4              =      SDA of PCA9685 A5              =      SCL of PCA9685 CONNECT THE SERVO MOTORS TO THE POINTS GIVEN ON THE BOARD[PCA9685] PCA9685 REQUIRES EXTERNAL CURRENT ALSO TO MAKE SERVO MOTORS WORK SO YOU NEED TO GIVE IT POWER THROUGH V+ AND GND. CODE OF THE PROJECT :- #include <Wire.h> #include <Adafruit_PWMServoDriver.h> #define SERVOMIN  125  #define SERVOMAX  575  uint8_...

In this tutorial you will get to know that how you can use keypad with ardunio to create security system with arduino and keypad. Material required Arduino Keypad Green LED Red LED Resistor (470 ohm) BREADBOARD Jumper wires Connections Connect Arduino 2-9 pins to KEYPAD Connect Arduino pin 12 to +ve of green LED Connect Arduino pin 11 to +ve of red LED Connect Arduino GND pin to -ve of both LED's CODE OF THE PROJECT :- #include <Keypad.h>  int green=11;  int red=12;  String password="2004";  String tempPassword="";  const byte ROWS = 4;  const byteCOLS =4;  char keypressed;  char keyMap[ROWS][COLS] = {  {'1','2','3','A'},  {'4','5','6','B'},  {'7','8','9','C'},  {'*','0','#','D'}   };  byte rowPins[ROWS] = {2, 3, 4, 5};  byte colPins[COLS] = {6, 7, 8, 9};  Keypad myKeypad = Keypad( m...

In this video i will show you that how you can connect your IFTTT with Raspberry Pi  and whenever you bring you hand closer to the IR sensor you get a alert message on your mobile phone. For this you need to have IFTTT app on your MOBILE PHONE. STEPS TO DO IT First open your IFTTT  app:- Then click on  Make your own applets from scratch Click on This After that search and click on  Webhooks Now click on Receive a web request Now enter  detected in Event Name column Now click on  That  Search  and click on Notification  Click on  Send a notification from the IFTTT app Now write Alert then click on insert ingredients  box located at right  then select OccuredAt after that write someone was in front of sensor Click  Finish CONNECTIONS Raspberry Pi 5V              =         VCC of IR sensor GND      ...

In this video I will show you that how you can connect IFTTT with Raspberry Pi and whenever you send message from your phone chat to raspberry pi and the LED connected to raspberry pi will glow. STEPS TO DO IT First you need to open terminal on your raspberry pi and write the following command:- bash <( curl - sL https : //particle.io/install-pi ) A fter writing it press enter. Then after few seconds it will ask you for an email, password and aname for your raspberry pi to setup an account. Then after setting it up you would have to open  build.particle.io   on your computer and sign in with the account you created on your raspberry pi terminal. Now an IDE will be opened like this :- After this copy the code given below and paste in the IDE :- void setup() {       pinMode(D2,OUTPUT);   digitalWrite(D2,LOW);     Particle.subscribe("your_code", myHandler);//change your_code with a unique code of your wish } voi...

In this tutorial you will get to know that how you can create an moisture detection system . Material requirements are given below :- MOISTURE SENSOR ARDUINO GREEN LED RED LED BRAEDBOARD JUMPER WIRES Working whenever the sensor detects moisture in the soil red LED glows otherwise green LED glows indicating no moisture .This can be used in gardens to make automatic watering system. CONNECTIONS ARDUINO GND          =     -ve of green , red LED and                           GND of moisture sensor 5V              =     VCC of moisture sensor 2                =      +ve of red LED 3                =      +ve of green LED  4                ...

In this tutorial you will get to know that how you can  make an arduino LED chaser. Material requirements are given below :- YELLOW LED's ARDUINO BRAEDBOARD JUMPER WIRES Working Whenever you give power to the Arduino the set of LED starts glowing one after the another LED.It becomes a patter looking like light is moving. CONNECTIONS ARDUINO GND          =     -ve of all LED's 2                 =      +ve of 1st LED 3                 =      +ve of 2nd LED  4                 =      +ve of 3rd LED 5                 =      +ve of 4th LED  6                 =      +ve of 5th LED CODE OF THE PROJEC...
