Hello,
I am trying to set a while loop in motion when a switch is pressed high, mainly the digital pin 2.
The code I have is below. I know the while loop works fine, but I am not sure about setting up the digital section to work when the switch is high. I have tried the best I could from the reference manual, but no joy. Any advice would be great.
An error I get is “‘D2’ was not declared in this scope”.
void setup()
{
Serial.begin(9600);
}
int var = 0;
void loop()
{
int buttonValue = digitalRead(D2);
if(buttonValue, HIGH)
{
while (var < 20)
{
Serial.println("Hello");
var++;
delay (2000);
}
}
}
Thanks in advance.
Seán
