## Article

### Dummy code:

**Setup:**

- clear logfile if button pressed within 2 sec. after startup

- write headers to CSV file

- optional: wait for button pressed to start logging

### **Loop:

- store timestamp

- make 30 readings, drop first five, calculate average (to filter jitter)

- calculate celsius value

- write to array

- repeat this for each sensor

- make comma separated string out of array

- if countdown is elapsed, write result to logfile

- write each result to LCD display

- wait until interwal time is elapsed

- start over again
