Hi guys,
Hoping to get some help as I’m struggling to get my button presses to register.
I have already followed the advice I found in this thread: https://forum.arduino.cc/index.php?topic=357607.0 but it doesn’t look like my button presses are registering.
I’m assuming I’ve made a rookie error with my wiring but I’m struggling to see it:
(Schematic attached)
Code driving it:
// arenaState:
// 0: Arena Disarmed
// 1: Standby
// 2: Fight in Progress
int arenaState = 0;
int imobilizedCounter = 0;
const int buttonStandbyPin = 2;
int buttonStandbyState = 1;
const int buttonArmedPin = 3;
int buttonArmedState = 1;
const int buttonCeasePin = 4;
int buttonCeaseState = 1;
const int buttonCounterPin = 5;
int buttonCounterState = 1;
const int ledDisarmedPin = 13;
const int ledStandbyPin = 12;
const int ledArmedPin = 11;
long currTime = 0L;
long arenaTimerStart = 0L;
long countTimerStart = 0L;
void setup() {
// Open serial communications and wait for port to open:
Serial.begin(57600);
while (!Serial) {
; // wait for serial port to connect. Needed for native USB port only
}
Serial.println("Arena ready");
pinMode(ledDisarmedPin, OUTPUT);
pinMode(ledStandbyPin, OUTPUT);
pinMode(ledArmedPin, OUTPUT);
pinMode(buttonStandbyPin, INPUT_PULLUP);
pinMode(buttonArmedPin, INPUT_PULLUP);
pinMode(buttonCeasePin, INPUT_PULLUP);
pinMode(buttonCounterPin, INPUT_PULLUP);
}
void loop() {
// read the state of the pushbutton values:
// NOTE: As we are using INPUT_PULLUP button press is LOW not HIGH
buttonStandbyState = digitalRead(buttonStandbyPin);
buttonArmedState = digitalRead(buttonArmedPin);
buttonCeaseState = digitalRead(buttonCeasePin);
buttonCounterState = digitalRead(buttonCounterPin);
if (buttonStandbyState == LOW) {
arenaState = 1;
Serial.println("Standby Button pressed");
}
if (buttonArmedState == LOW and arenaState == 1) {
arenaState = 2;
// start 3min countdown
arenaTimerStart = currTime;
Serial.println("Start Button pressed");
}
if (buttonCeaseState == LOW and arenaState >= 1) {
arenaState = 0;
Serial.println("Cease Button pressed");
}
if (buttonCounterState == LOW and arenaState >= 1) {
if (imobilizedCounter == 1) {
imobilizedCounter = 0;
} else {
countTimerStart = currTime;
imobilizedCounter = 1;
}
Serial.println("Imobilised Button pressed");
}
switch (arenaState) {
case 0:
digitalWrite(ledDisarmedPin, HIGH);
digitalWrite(ledStandbyPin, LOW);
digitalWrite(ledArmedPin, LOW);
break;
case 1:
digitalWrite(ledDisarmedPin, LOW);
digitalWrite(ledStandbyPin, HIGH);
digitalWrite(ledArmedPin, LOW);
break;
case 2:
digitalWrite(ledDisarmedPin, LOW);
digitalWrite(ledStandbyPin, LOW);
digitalWrite(ledArmedPin, HIGH);
// Check to see if 10sec are up
if(imobilizedCounter == 1) {
if(currTime >= arenaTimerStart + (10*1000L)) {
arenaState = 0;
}
}
// Check to see if 3min are up
if(currTime >= arenaTimerStart + ((3*60)*1000L)) {
arenaState = 0;
}
break;
default:
digitalWrite(ledDisarmedPin, HIGH);
digitalWrite(ledStandbyPin, LOW);
digitalWrite(ledArmedPin, LOW);
}
currTime++;
}
Note: I know my timing code is silly and needs an RTC but I don’t think it’s having an impact on my current issue.
