First of all, im new to this forum as well as Arduino and electronica and programming in general, so please no harsh words :p
Maybe it isnt the right subforum to post this, but while doing project 3 (Love-o-meter) i was wondering why there isnt any resistor going from the temperature sensor towards ground?
Thanks for the answer!
I am not sure on this and it seems obvious but...
It just doesn't need one. It can take up to 7V according to the spec sheet.
Most LEDs are a different story however...
