// Connect the pushbutton and relay to the Arduino board. 
// The pushbutton should be connected to a digital input pin, 
// and the relay should be connected to a digital 
// output pin. 

// Also, you can connect the VCC of the relay to the 5V of Arduino, 
// and the GND to the GND of the 
// Arduino.

// In the “setup()” function, set the digital input pin for the pushbutton and digital 
// output pin for the relay 
// using the “pinMode()” function and open the serial communication with the computer 
// for monitoring the state 
// of the relay. For example, you could connect the pushbutton to digital pin 2 and 
// the relay to digital pin 3.
