I've created a program to read temperature from 4 sensors, get an average and close/open 4 relays according to min/max values. Right now I'm trying to add a 16x2 LCD display to show those temperatures live instead of having to connect the Arduino to the serial bus and I wrote this:
#include <Wire.h
I practically never use recursion, but I was writing a method just now and realized that I could probably use it in this case.
Basically I need to get the ID of a record in a table, but if that record doesn't exist, I need to add it and then return it.
