Hello everyone,I’ve attempted to make a thermometer using an LCD screen and 16 LEDs. My intention is to assign one LED to a range of temperature. So, I made this code and when I try to switch them off at a certain temperature they don’t. I just tried with the first red LED starting from above and then I will with the rest.
I used the circuit shown in the picture repeated 16 times and the breadboard with the circuit implemented. What have I done wrong? I appreciate your help.
