Question

Write Arduino code to read the input state of pin3 and output the value to the onboard LED.

(a) Create hardware that causes pin 3 to read a high value when a button switch is pushed and a low value when the switch isn’t pushed. Breadboard the needed hardware.

This is what I have so far, and I need extra help on the code. Or, I'm unsure if this is the correct appoarch. The hardware I have is my Ardunio UNO, LED red light, and 1kilo-Ohm resistor.

int outPin = 3;

void setup()
{
pinMode(outPin,OUTPUT); //initalize pin 3 on Ardunio
pinMode(pushbutton; INPUT); //initalize output button
}

void loop()
{
button = digitalRead(pushbutton);

if(button == HIGH)
{
digitalWrite(outPin, HIGH);
delay(100);
digitalWrite(outPin, LOW);
}
else
{

???
}
}

Explanation / Answer

U have used the correct approach but it just need little changes in void loop

Void loop()

{

button = digitialRead (pushbotton);

if (pushbotton==High)

{

digitalWrite (outPin , HIGH);

// this is the case when button is pushed, it will make LED at pin3 glow

delay(2000); // 2 seconds delay

}

else

{

digitalWrite ( outPin , LOW );

// When switch is not pushed theLED will remain off

delay(2000);

}
