I am making a project where I have a temperature sensor and a Dimmer to trigger some LEDs (soon gonna be changed by magnetic valves.) Well The idea is then the value from the dimmer is equals or smaller than the temperature the LEDs is changing value too.
I Now have a problem. Let's say i have set the wished temperature to be 25 Celsius. Then my temperature sensor is reaching right between 24,9 C and 25 C it begins to jump between these two values until the temperature reach a bit over 25 Celsius.
Well because I will have some magnetic valves to control water flow, I will then have to get this problem solved or else my valve will begin to open and close really fast for some time..
So can i make some kind of "Dead point" let's say from -0.5 to 0.5 from the wanted value, where noting is happening, or how else do i handle this problem?
I have under this post an illustration of my idea of a system if that helps to understand what i want to make!
Hope you can help me!
