Steps

1. Make sure the components are working properly.
2. Connect Raspberry Pi Pico board VBus and GND pin to the bread board by using wires.
3. Connect 220 Ω Resistor to the LED Anode (+) pin and cathode (-) pin to Gnd.
4. Connect 220 Ω Resistor another pin to GP16.
5. Connect 10 k Ω Resistor to the switch button.
6. Connect switch button another pin to the Raspberry Pi Pico pin GP17.
7. When we press the push button LED blinks.
8. Check the Arduino program.
9. Check the circuit connections.
10. Run the Arduino program.

Arduino Program

int ledPin = 16;
int buttonPin = 17;

void setup()
{
  pinMode(ledPin, OUTPUT);
  pinMode(buttonPin, INPUT);
}


void loop()
{  
  int button = digitalRead(buttonPin);
  if (button==HIGH)
  {
    digitalWrite(ledPin,HIGH);
  } 
  else
  {
    digitalWrite(ledPin, LOW);
   }
}
