Automatic Barrier Opening system Hello! I am Shlok Jain. I have made Automatic Barrier Opening System. It's a very easy task to make this. If you hane not viewed my youtube video then go and view it. Here it is. Also don't forget to like, share, and subscribe my channel.   Materials Required Arduino UNO Ultrasonic sensor Servo motor some jumper wires breadboard Steps to make it Step 1: Make connections according to given circuit diagram. Step 2: Now download arduino IDE. Now open application. Clear everything written on it. And paste following code there. CODE OUTPUT Copy code #include < Servo . h > int trig = 2 , echo = 3 ; Servo servo ; void setup ( ) {   servo . attach ( 5 ) ;   pinMode ( trig , OUTPUT ) ;   pinMode ( echo , INPUT ) ; } void loop ( ) {   long samay , dist ;   digitalWrite ( trig , LOW ) ;   d...

Thief Detecting device (Arduino ) Hello! I am Shlok Jain. I have made here a thief detecting robot. It's a very easy task to make this If you hane not viewed my youtube video then go and view it. Here it is. Also don't forget to like, share, and subscribe my channel. MATERIALS   REQUIRED  1:      Arduino UNO board 2:      Ultrasonic sensor 3:      Buzzer (optional) STEPS    TO    MAKE   IT. STEP 1 : Connect the ultrasonic sensor with the arduino uno board with ultrasonic sensor like this: If you are using buzzer then connect negative terminal to GND and positive terminal to pin 13. STEP 2: Connect the arduino board with computer by cable that comes with it. STEP 3: Download Arduino IDE from https://www.arduino.cc/en/software   . Now paste the given code in that application and click that arrow symbol on upper left corner to upload the code. CODE OUTPUT ...

DISTANCE MEASURING DEVICE (Arduino based) Hello! I am Shlok Jain. I have made here a distance measuring device with only ultrasonic sensor and arduino uno board. It's a very easy task to make this. I have not used jumper wire or breadboard or LCD screen here. If you have not viewed my youtube video then go and view it. Here it is. Also don't forget to like, share, and subscribe my channel. MATERIALS REQUIRED Arduino UNO board       2. Ultrasonic sensor STEPS TO MAKE IT STEP 1: Connect ultrasonic sensor with arduino uno board. as shown in figure. Leave first three pins and apply sensor directly to board. STEP 2:  Connect arduino board with computer with cable that comes with arduino uno Download Arduino IDE and paste given code in that application. Now upload the given code by clicking the arrow symbol at upper left of computer screen. int trig=12; int echo=13; void setup() { pinMode(trig,OUTPUT); pinMode(echo,INPUT); pinMode(11,OUTPUT); digitalWrite(11,HIGH)...
