RC Invention

ABOUT THIS PROJECT About This project is about the simple hack of voltmeter by Arduino. The main reason behind making this is from my personal experience, when I was performing one experiment in the lab, I could not find a voltmeter so I made this hack to fulfill my requirement and also I think it will help others too. Good project for beginners which uses basic concepts, yet a power full tool. While running the code, you can find the output on the serial monitor. Calculating Voltage Formula for calculating voltage: Vout = (Val * 5.0 ) / 1024.00 ; Here in these formula Val is the value that is read by Arduino as analog input, which is further multiplied by the voltage that is been supplied by Arduino and thus to get the Vout it is divided by the cycle of time that is covered after every bit to get the value. Vin = Vout / ( R2 / R1 + R2 ) By this formula we can find the Vin that will be around 0, which indirectly means we are creating ground. NOTE: Here there is no restriction on usi...

Self driving car using Arduino.               Self driving robot is an intelligent device which can automatically sense the obstacle in front of it and avoid them by turning itself in another direction. This design allows the robot to navigate in an unknown environment by avoiding collisions, which is a primary requirement for any autonomous mobile robot. The application of obstacle Avoiding robot is not limited and it is used in most of the military organization now which help carry out many risky jobs that can not be done by any soldiers.              This project we are going to use Arduino microcontroller, Ultrasonic sensor, Servo motor, gear motor, wheel, motor driver and battery. Here an Arduino id used to control the robot and an Ultrasonic sensor is used to sense the obstacle in the path and calculate the distance between the robot and obstacle and change the direction to continue moving. Compo...

NEW YEAR GIFT BOX USING ARDUINO.   Hi friends, how are you,      Today we are going to make a NEW YEAR GIFT BOX using Arduino, Requirement 1.       Arduino Uno or any version. 2.       Ultrasonic sensor HC-SR04. 3.       Servo motor SG90. 4.       Jumper wire. 5.       Gift box.

how to make smart blind stick.       Today we are going to make an Intelligent blind stick for blind people. Their life is always depending on others. They can’t walk without the help of others. Using this intelligent blind stick, a blind person can walk without any helps. The intelligent blind stick automatically detects the obstacle and water in front of the person and gives him a response to the person by a warning sound and vibrating the stick. The person can also find his/her stick with the help of a remote. Through this intelligent blind stick, the blind person can aware the any obstacles and water in front of him. How to make intelligent blind stick (part-01) watch the video.... Here are the parts to make this project   1.      Arduino UNO / nano/ mega/ pro any one    2.      Ultrasonic sensor HC-SR04.       3.       433Mhz RF modul...
