as a beginner im stumbelling on a early problem. Im trying to let my arduino uno read a lm35 temperature sensor and make him output the degrees in a led setup.
whats happening now is that it works from degrees 1-9 perfectly, but the second you have 2 digits it doesnt work. It wil see anything between 10-19 as 1, 20-29 as 2 and so on.
how can i let my arduino send a digital output that is 2 digit in stead of one?
Much thanks in advance
