DIY How to make a Conductive paint homemade.

      

What is conductive Paint?

Conductive Paint is a non-toxic electrically conductive material, which is easy to use as poster paint, and dries in under 5 - 10 minutes to become conductive. There are so many different types of conductive paints and inks are available on Amazon, Banggood, and many more But these are so expensive that why I decided to make our own conductive paint it is Very cheap and easy to make.

Conductive paint provides a different method of combining with electronics as it can be applied to almost any surface, including paper, wood, cardboard, walls, textiles and many more.

We need this material to make conductive paint.

          1.       Dead cell

          2.       Glue

          3.       Water

          4.       A Jar

   

Graphite powder (From Battery)                

Glue

Step to make:

1. Take a dead battery and gain graphite powder (make sure battery doesn't contain alkaline).

2. Crushing graphite into a small tiny bit.

3. Find a small sealed container, Add 2 teaspoons of graphite powder. Graphite is a good conductor of electricity. It is something like metal, graphite contains delocalized (free) electrons.

4. Add in a small amount of glue (to make sticky on any substance) and mix well.

5. If the mix is too heavy add a little more glue. The final mix should be fairly thick, but still paintable.

Requirement  

      1.   Arduino Uno

      2.   1 x LEDs (5mm)

      3.   1 x 1M ohms  

      4.   Breadboard

      5.   Jumper wires

  6.   Conductive Paint paper     

Step to create:

1.      Take an LED, connect Positive pin to GND pin of Arduino Uno and Negative pin to 12 pins of Arduino Uno.

2.     Connect a 1M ohm resistor to pin 4 and pin 2 of Arduino pin.

3.      Connect a male to male jumper wire to pin 2 of Arduino and at the end of the male jumper to attach conductive paint paper.

4. Now the circuit is ready………Upload the code…….Enjoy it.

Code

#include <CapacitiveSensor.h>

CapacitiveSensor cs_4_2 = CapacitiveSensor(4,2);//1M resistor between pins 4 & 2, pin is sensor pin,add a wire and or foil if desired.

void setup() {

  // put your setup code here, to run once:

  cs_4_2.set_CS_AutocaL_Millis(0xFFFFFFFF); //turn off autocalibrate on channel 1 -just as an example

  Serial.begin(9600);

  pinMode(13, OUTPUT);//set a pin 7 as a output 

}

void loop() {

  // put your main code here, to run repeatedly:

long total = cs_4_2.capacitiveSensor(1000);

Serial.println(total);

 if(total >= 1000){

  digitalWrite(13, HIGH);

  }

  else{

    digitalWrite(13, LOW);

    }

}
