HELLO THERE,

In this tutorial I will show you , how to make automatic contactless soap dispenser which is fully DIY

if you like it then consider supporting me by subscribing my channel ARDUINO MAKER. So get ready to be inspired.....! you can also watch my youtube video

THINGS YOU WILL NEED :-

1. ARDUINO NANO
2. SEVO
3. IR SENSOR
4. SOAP BOTTLE

After getting all supplies you can start connecting all things and securing them by soldering all connections properly. All connections are given above in the circuit diagram

So, now after completing all connections its time to modify the soap dispenser so we could use it for our purpose

you can modify it by making some holes on the top nozzle as shown in the above picture

Now, after completing the above steps you can start gluing all the components in place as shown in above pictures

After this you will need a wire or sting to connect the dispenser with the servo's shaft through holes as shown above

Now, upload the code below

#include<Servo.h>
Servo myservo;
int pos = 180;
void setup() {
  pinMode(2,INPUT);
  myservo.attach(3); 
}
void loop() {
  int hsense=digitalRead(2);
  if((hsense==HIGH))
  {
    myservo.write(0);
    }
  else
  {
     myservo.write(180); 
  }
}
