Hello,
So basicly i started learning about electronics 2 moths ago so i know only the basic stuff. Now im supposed to do my first project and i thought of making a simple temperature based device. The idea is that when the temperature is lets say 21 C a white diod will light, if it is 1 degree colder 1 blue diod will light, one degree warmer 1 red diod will light and so on. I was thinking of using 3 blue and 3 red diods. So my idea of making it work was to use a NTC thermistor + an operational amplifier. the thing is im not sure if it will work and can i use the same NTC to all the diodes or i need 7 diffrent ones?
As I said before I really know little about electronics so if there is a simpler or a better way to make it please tell me i also wanted to add one 7seg display so it would show how many degrees is under or over the 21C but i think it is still too complicated for me
P.S Its my first thread on this forum so sorry if i posted it in a wrong place
