i've been having some issues with the arduino uno. i have written a code for it but the board keeps getting locked into a loop and running the alarm process regardless of what i do. also for some reason the output marked red goes high whenever i disconnect the proxy, that is if the alarm doesn't continue to sound. here is a sample of the code. i thought it might be the board but i have bought two and they both do the same thing. any suggestions?
const int Red = 7;
const int Green = 4;
const int Blue = 6;
const int Yellow = 8;
const int Proxy = A0;
const int Redin = A1;
const int Greenin = A2;
const int Bluein = A3;
const int Yellowin = A4;
const int Alarm = 9;
int pval = 0; //proxy value
int rval = 0; //red value
int gval = 0; //green value
int bval = 0; //blue value
int yval = 0; //yellow value
void setup()
{
pinMode(Red, OUTPUT);
pinMode(Green, OUTPUT);
pinMode(Blue, OUTPUT);
pinMode(Yellow, OUTPUT);
pinMode(Proxy, INPUT);
pinMode(Alarm, OUTPUT);
pinMode(Redin, INPUT);
pinMode(Greenin, INPUT);
pinMode(Bluein, INPUT);
pinMode(Yellowin, INPUT);
}
void loop()
{
pval = analogRead(Proxy); //read proxy value and store it
if (pval < 1000) {
digitalWrite(Alarm, LOW);
digitalWrite(Red, LOW);
digitalWrite(Green, LOW);
digitalWrite(Blue, LOW);
digitalWrite(Yellow, LOW);
}else{
//Read the values
rval = analogRead(Redin);
gval = analogRead(Greenin);
bval = analogRead(Bluein);
yval = analogRead(Yellowin);
}
if (rval > 1000){
digitalWrite(Red, HIGH);
digitalWrite(Green, LOW);
digitalWrite(Blue, LOW);
digitalWrite(Yellow, LOW);
digitalWrite(Alarm, LOW);
delay(2000);
}
else if (gval > 1000){
digitalWrite(Red, LOW);
digitalWrite(Green, HIGH);
digitalWrite(Blue, LOW);
digitalWrite(Yellow, LOW);
digitalWrite(Alarm, LOW);
delay(2000);
}
else if (bval > 1000){
digitalWrite(Red, LOW);
digitalWrite(Green, LOW);
digitalWrite(Blue, HIGH);
digitalWrite(Yellow, LOW);
digitalWrite(Alarm, LOW);
delay(2000);
}
else if (yval > 1000){
digitalWrite(Red, LOW);
digitalWrite(Green, LOW);
digitalWrite(Blue, LOW);
digitalWrite(Yellow, HIGH);
digitalWrite(Alarm, LOW);
delay(2000);
}
else{
digitalWrite(Red, LOW);
digitalWrite(Green, LOW);
digitalWrite(Blue, LOW);
digitalWrite(Yellow, LOW);
digitalWrite(Alarm, HIGH);
delay (400);
digitalWrite(Red, LOW);
digitalWrite(Green, LOW);
digitalWrite(Blue, LOW);
digitalWrite(Yellow, LOW);
digitalWrite(Alarm, LOW);
delay (200);
digitalWrite(Red, LOW);
digitalWrite(Green, LOW);
digitalWrite(Blue, LOW);
digitalWrite(Yellow, LOW);
digitalWrite(Alarm, HIGH);
}
}
