You were right about the upper exclusive, I've done that to test it
#include <LiquidCrystal.h>
LiquidCrystal lcd(8, 9, 4, 5, 6, 7);
int res =0;
long dicea;
void setup() {
Serial.begin(9600);
lcd.begin(16, 2);
}
void loop() {
res = analogRead(15);
if (res < 350) {
dicea = random(1,7);
lcd.setCursor(0, 0);
lcd.print(dicea);
delay(5000);
}
lcd.clear();
}
And I saw another problem, when I reset my program, it show the same numbers, how can I make it look like a true number generator...
thanks
