Ok, in the following link is an album with the various pictures I took, as well as some pictures of the multimeter readings; I also included a picture of the basic schematic: http://imgur.com/a/3gr5R
My code is very basic, I just did it to see if there were any problems with the readings (which there are :P):
int sensePin = A0;
void setup()
{
Serial.begin(9600);
}
void loop()
{
Serial.println(analogRead(sensePin));
delay(500);
}
