Introduction: Arduino Temperature Sensor
I am an eleven year old kid. I just started Arduino a few years ago. Arduino used to be really tough so my goal is to help beginners like I was.
Step 1: This Will Be Your Inventory
You will need:
5 jumper wires
1 LM35 temperature sensor
1 Arduino Uno
1 breadboard
Step 2: This Is the LM35 Temperature Sensor.
This looks a lot like a transistor. I've posted an image of a closeup so that you don't get confused.
Step 3: Wire the Temperature Sensor Like This
Notice that the red wire is going to 5v, the black wire to ground, and the blue to analog read pin 0.
Step 4: Here Is the Code
This is the code:
void setup() {
Serial.begin(9600); // set up the connection between the arduino board and the computer.
}
void loop() {
float x; // we are telling it that there is a random decimal number which we will call x.(this being the value that the temperature sensor has read.)
x = analogRead(0); //read this number through the analog input pin that we plugged the middle leg of the sensor into.
Serial.print(x); // display this number on the serial monitor
}
