How to make ' As you sow, so you shall reap ' Device at home

This project is a very simple type of Arduino project which works like an Artificial Intelligence. This circuit counts the number of times the speaker taped and report back the number of tapes with tones.

         

      This circuit is only for fun purposes by using the Arduino microcontroller.

                                       Circuit diagram...






Coding 

byte tapCount = 0;

long int tapTime = millis();


void setup()

{

Serial.begin(9600);

}


void loop()

{

int sensorValue = analogRead(A0);

Serial.println(sensorValue);


if(sensorValue > 40) //detect a tap

  {

    delay(70);

    tapCount = tapCount + 1; //increment tap count

    tapTime = millis(); //record current system time

  }


if(tapTime < (millis() - 400)) //if more than 0.4 seconds have elapsed since last tap

{

  for(int x=0; x < tapCount; x++)

    {

      pinMode(A0,OUTPUT);

      tone(A0, 1500);

      delay(200);

      noTone(A0);

      delay(200);

      pinMode(A0,INPUT);

    }

  tapCount = 0;

}


delay(5); // delay in between reads for stability

} //loop

How to make talking Voltmeter at home

 Homemade talking voltmeter using Arduino   It's easy to make a simple digital voltmeter using an Arduino, Audio amplifier and Speaker It's relatively simple to use an Arduino to measure voltages. The Arduino has several analog input pins that connect to an analog-to-digital converter (ADC) inside the Arduino. The Arduino ADC is a ten-bit converter, meaning that the output value will range from 0 to 1023. We will obtain this value by using the analogRead() function. If you know the reference voltage--in this case we will use 5 V--you can easily calculate the voltage present at the analog input.   Requirement 1. Arduino uno/nano. 2. Audio amplifier. 3. Speaker. 4. 100K ohm resistor. 5. battery .

IR Sensor Circuit Diagram IR communication is very common wireless communication technology.IR communication is easy to use. IR Communication generally comprises of IR transmitter and IR receiver. The most common use if IR communication is remote controls of different appliances like RC toys, Music systems,TV remote control, and some embedded projects consists of IR Modules where they can be used as a proximity sensor, distance measurements, and security alarm, etc. in this project, we have demonstrated the functioning of a simple IR Module using NE555 Timer IC and some electronic components. the aim of this project is to make a different type of IR sensor that can work both inside and outside of the home with the help of 555 timers IC. in this project we have used TSOP1738 IR receiver to receive infrared signal with some frequency and a simple IR LED to transmit the IR signals, The circuit diagram, components, and the working is explained in the video :--) for any bus

How to make voltmeter using Arduino

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
