We are use piano in our traditional event which has plastic button. After pressing button we can hear sound of swaras ( SA,RE,GA,MA,PA,DHA,NI,SA) instead of this type of piano we can use touch sensor instead of button.
Sr.no. Material Quantity
1. Arduino Mega 1
2. 47 K resistor 7
3. Copper foil half sheet
4. Connecting wire 3mtr
5. Speaker 1
6. Laser cutting Box 1
First take copper foil and printed sketch paper of 7 swaras (Sa, Re,Ga,Ma,Pa,Dha,Ni). Cut copper foil as size of sketch and paste it on sketch paper.
Tell them how to sketch 7 swaras.
Solder two different wire(red and black) to each terminal of resistor using soldering gun and soldering material .
Introduce them with how to solder.
Solder first terminal of each 7 swaras resistor( of red wire ) with copper foil and also solder second terminal of resistor (of black wire) to each analog pin of arduino mega board respectively.
Help them soldering to copper foil and arduino mega.
Combine all red wire of each swaras and make only one single wire. now connect single red wire to 5v pin of arduino.
Make program of Piano in arduino software and upload code into arduino board.
Introduce them with arduino software.
When we put our finger on each copper foil then circuit get ground and complete it. Then we hear sound of 7 swaras (Sa,Re,Ga,Ma,Pa,Dha,Ni) respectively.
Introduce them with how circuit complete.
Thank you for your fab contribution!
