Story

Hello World! I made another example for one of the Sensors from my arsenal :)

This time the Mercury Switch Module KY-017.

We are going to turn on and off a lamp with it, the code is very basic and easy to understand.

Follow the next step for the Schematic Code and Parts list!

Step 1: Schematic Code & Parts List

Just wire it up like the schematic and upload the code.

Parts List.

Arduino Uno, I used the Robotdyn Uno as i always do. Until it breaks:) then i use a new one! lol

1 Channel relay KY-019

Mercury Switch Module KY-017

1 Led of any color you want.

Jumper wires MM/FF/FM

Lamp socket + Lamp and power cable (optional to add to the relay)

Good luck!

Follow me for more! I will write codes and make schematics for all sensors i got.

About 40 sensors!

This example will show you how a Mercury switch works.
This example is very basic and easy to understand.
It will turn on a relay when tilting the switch.
You can add a lamp or any device to the relay.

int BlueLed = 9;
int KwikSwitch = 8;
int Relay = 7;
int val;

void setup() 
{
pinMode (BlueLed, OUTPUT);
pinMode (Relay, OUTPUT);
pinMode (KwikSwitch, INPUT);

}

void loop() 
{
  val = digitalRead (KwikSwitch) ;
  if (val == HIGH)
  {
    digitalWrite (BlueLed, HIGH);
    digitalWrite (Relay, HIGH);
  }
  else
  {
    digitalWrite (BlueLed, LOW);
    digitalWrite (Relay, LOW);
  }
  
}
