Giland:
the for loop works if you set it up as a function instead of inside the void loop.When the if loop is done, it would automatically return to void loop and look for another button press.
I can't interpret either of those sentences in any way that makes sense.
how about
the for command works if used in a separate function instead of being inside the void loop().
when the if loop has i in the function reach 5 (no longer less than 5), it will return back to the void loop() and wait for another button press.
for example
void loop ()
{// general code to look for button press, current state, etc etc
if (button == 3) buttonstate3;
}
int butttonstate3()
{
{for(int i = 0; i < 5; i++)
{
Serial.println(i);
digitalWrite(7, LOW);
digitalWrite(8, LOW);
digitalWrite(9, LOW);
delay(400);
digitalWrite(7, HIGH);
digitalWrite(8, HIGH);
digitalWrite(9, HIGH);
delay(400);
}
button = 4;
}}
