My students are trying to trouble shoot how to use a push button switch instead of a tilt switch.
here is their code.
#include <LiquidCrystal.h>
LiquidCrystal lcd(12, 11, 5, 4, 3, 2);
const int switchPin = 6;
int switchState = 0;
int prevSwitchState = 0;
int reply;
void setup() {
lcd.begin(16, 2);
pinMode(switchPin,INPUT);
lcd.print("Ask the");
lcd.setCursor(0, 1);
lcd.print("Crystal Ball!");
}
void loop() {
switchState = digitalRead(switchPin);
if (switchState != prevSwitchState) {
if (switchState == HIGH) {
reply = random(0,9);
lcd.clear();
lcd.setCursor(0, 0);
lcd.print("Crystal Ball Says:");
lcd.setCursor(0, 1);
switch(reply){
case 0:
lcd.print("yes");
break;
case 1:
lcd.print("Most Likely");
break;
case 2:
lcd.print("Certainly");
break;
case 3:
lcd.print("Probably");
break;
case 4:
lcd.print("Unsure");
break;
case 5:
lcd.print("Come Again");
break;
case 6:
lcd.print("Doubtful");
break;
case 7:
lcd.print("No");
break;
}
}
}
prevSwitchState = switchState;
}
I am attaching a few pictures of our circuit.
Thank You
