WEEK 11
WEEK ASSIGNMENT:
INPUT DEVICES
LM35 is a temperature sensor calibrated to an accuracy of 1 ° C . Its measurement range is from -55 ° C to 150 ° C . The output is linear and each degree Celsius equals 10 mV , thus : C = 1500 mV 150 .
I chose a temperature sensor being an entry that collects and processes environmental data as is the temperature.
An analog temperature sensor such as LM35 increases the level of the voltage reaching the plate in proportion to the temperature.

INPUT:
To store the two possible values LOW or HIGH in a variable called "reading"
I did a little exercise to measure room temperature and display it on my PC. The assembly did not take more than a couple of minutes and we could see the scheme clearly. The leg Vs + 5V pin goes to the Vout leg to pin we use for reading, in this case 0, and the remaining GND to GND . Keep in mind that the drawing is made LM35 view from the legs
To store the temperature we used the following variable:
>float temperature ; // Store the value read here
pinentrada int = 0; // Use the pin A
To communicate from your computer to the controller so you can display the data on screen.
>And the code looks like
void loop ()
temperature = analogRead ( pinentrada ) ; // Reading pin A0
temperature = (temperature / 1023 * 5 / 0.01) ; // "Translates" the value read degrees
Serial.print (temperature ) ; // Write the value of the temperature through the serial port
Serial.print ( " Celsius degrees \ n"); // Write units
delay ( 1000 ) ; // Wait one second
We loaded the code on the plate and we just had to click on the serial monitor icon
This temperature sensor was used for my final project
