We watch TV Daily. One of the biggest problems we face while watching TV is The Remote Being Lost. It is such a big headache keeping track of our TV Remote. Sometimes we even leave the Remote in another room and wonder where the remote is. To solve the problem, I created the Remote Finder. So this device has an app which is connected to it. When the remote is lost we can simply go to the app and type 1 for the buzzer to BEEP and we can simply type 0 if we find the remote to deactivate the buzzer.
Materials Required
1 X Arduino Data Transfer Cable for Nano or Uno
1 X HC - 05 Bluetooth Module
1 X Piezoelectric Buzzer
1 X Breadboard or Protoboard
1 X ATmega 328P
Build the Circuit

Build the circuit on a breadboard as given in the Fritzing sketch above. Here are the connections:-
HC - 05 Bluetooth Module:-
1 HC - 05 TX --- Arduino RX
2. HC - 05 RX --- Arduino TX
3. HC - 05 VCC --- Arduino 5V
4. HC - 05 GND --- Arduino GND
Buzzer:-
1. Buzzer +ve --- Arduino D13
2. Buzzer -ve --- Arduino GND
Upload Code
![code.PNG](/proxy/?url=https://content.instructables.com/F9H/6RXQ/JUQS8N46/F9H6RXQJUQS8N46.png&filename=code.PNG)
1. Open up your Arduino IDE
2. Copy the code given below and paste it in the IDE :-
char data = 0;
void setup() {
Serial.begin(9600);
pinMode(13, OUTPUT);
}
void loop () {
if(Serial.available() > 0) {
data = Serial.read ();
Serial.print(data);
Serial.print("\n");
if (data == '1')
digitalWrite(13, HIGH);
else if(data == '0')
digitalWrite(13, LOW);
}
}
3. Connect the Arduino to the Computer with the help of USB cable.
4. Important - Remove the TX and RX wires connected to the Arduino from the Bluetooth Module before uploading the code.
5. Select the COM Port and the Board (Arduino / Genuino Uno).
6. Click Upload
Connecting the App

![s2 terminal.PNG](/proxy/?url=https://content.instructables.com/FBQ/SL0C/JUQSLNA1/FBQSL0CJUQSLNA1.png&filename=s2 terminal.PNG)
After uploading the code, connect the RX and TX pins of the Bluetooth module to the Arduino just like before.
Now Open up your Android Device, then follow these instructions:-
1. Go to Settings and then click on Bluetooth on your device.
2. Select the Bluetooth Module Mainly Named " HC - 05 ".
3. Enter the passcode which is mainly "1234".
4. Download the APP S2 Terminal from the Play Store.
5. After Downloading, open the App.
6. Click on " Connect A Device " Option on the top right corner and select the Bluetooth Module.
Testing
After connecting the Bluetooth module, type 1 on the bar for the buzzer to beep. You can stop the buzzer by typing 0.
If it is not working try the following:-
1. Re-upload the code.
2. Check the connections.
Shrinkify

To shrink the project for attaching it to a remote do the following things:-
1. Change the Arduino board to an ATmega 328P for increasing the battery's life span
2. To make this portable, remove the USB Plug and attach a 9v or 4 x AA Battery pack
+ve Terminal of the battery --- Vin pin of Arduino
-ve Terminal of the battery --- GND pin of Arduino
3. Remove the Breadboard and solder the components into a perf board or solder them directly by wires.
Final Touches

After soldering, enclose the project mainly in a box or else if you can dare, you can open the remote and store the project there and don't forget to make a hole for holding the battery outside.
