Temperature Problem

Development Boards Arduino

I bought Spakfun Inventors Kit V3.2

This is my sketch:

#include <SoftwareSerial.h>

SoftwareSerial XBee(2, 3); // RX, TX

const int PinUno = 3; //digital

const int PinDos = 4; //digital

const int Temp = 1; //Analog

float voltage, degreesC, degreesF;

const int buzzer = 9; //digital

const int songLength = 18;

char notes = "cdfda ag cdfdg gf ";

int beats = {1,1,1,1,1,1,4,4,2,1,1,1,1,1,1,4,4,2};

int tempo = 150;

void setup() {

XBee.begin(9600);

pinMode(PinUno, OUTPUT);

pinMode(PinDos, OUTPUT);

pinMode(buzzer, OUTPUT);

}

void loop() {

if (XBee.available()) {

int inByte = XBee.read();

switch (inByte) {

case ‘5’:

digitalWrite(PinDos, HIGH);

break;

case ‘6’:

digitalWrite(PinDos, LOW);

break;

case ‘7’:

digitalWrite(PinUno, HIGH);

break;

case ‘8’:

digitalWrite(PinUno, LOW);

break;

case ‘1’:

voltage = analogRead(Temp) * 0.004882814;

degreesC = (voltage - 0.5) * 100.0;

degreesF = degreesC * (9.0/5.0) + 32.0;

XBee.print("Holmann Voltage: ");

XBee.print(voltage);

XBee.print(" Grados C: ");

XBee.print(degreesC);

XBee.print(" Grados F: ");

XBee.println(degreesF);

break;

case ‘2’:

int i, duration;

for (i = 0; i < songLength; i++) {

duration = beats * tempo;
if (notes == ’ ') {
delay(duration);
} else {
tone(buzzer, frequency(notes), duration);
delay(duration);
}
delay(tempo/5);
}
break;
}
}
}
int frequency(char note) {
int i;
const int numNotes = 8;
char names[] = { ‘c’, ‘d’, ‘e’, ‘f’, ‘g’, ‘a’, ‘b’, ‘C’ };
int frequencies[] = {262, 294, 330, 349, 392, 440, 494, 523};
for (i = 0; i < numNotes; i++) {
if (names == note) {
return(frequencies);
}
}
return(0);
}
When I press 5 a red led turns on (ok)
When I press 6 red led turns off (ok)
When I press 7 a relay turns a table light On (ok)
When I press 8 relay turns my table light Off (ok)
When I press 2 the buzzer plays a song (ok)
Howerver:
When I press 1 (Analog pin) I get the temperature and at the same time my
table light turns on for a milisecond and then turns off.
Any idea what is happening?.

SoftwareSerial XBee(2, 3); // RX, TX

const int PinUno = 3; //digital

case '7':
 digitalWrite(PinUno, HIGH);
 break;
 case '8':
 digitalWrite(PinUno, LOW);
 break;

Do you see the common thing in these 3 code parts?

Another hint: Does the XBee RX led turn on when you turn off the table light with command ‘8’? (That is, assuming the shield or explorer you have the XBee on has those RX, TX leds)
