LM34 Issues

Cyber

I don't know where to start with my LM34 Sensor, and anything I have found on forums, the powerpoint, or on other websites does not seem to assist with my issues.

We are in BASIC Editor using BS2, and we have the language to 2.5.

I do have a code that I thought might work that ended up not helping:

---

// LM34 temp sensor connected to analog pin A0
const int tempSensor = A0;

void setup() {
Serial.begin(9600);
}

void loop() {
Serial.println(analogRead(tempSensor), DEC);
delay(300);
}

Edit: 0. Your sample code is C. The Basic Stamp is programmed in BASIC. End Edit

1. You can use an ADC and read the voltage the LM34 is producing.

2. You can turn the LM34 into a current source and use RCTIME. Here are pointers to a couple of threads: Look at the comments from Tracy Allen.

More specifically, your code is for an Arduino. It won't work with a BS2.

In addition to the thread Tom pointed out, there's a more involved discussion here, which includes calibrating the unit:

but note it is pre-PBASIC 2.5. It should still work for you, though.
