I'm a beginner at Arduino and ı wanna do a project about temperature sensors. What do I need to do to run it in a certain temperature range?
For example, operating the heater in the range of 22-26 degrees.
if (temp<=sinirdeger1 || temp<=sinirdeger2)
Well would that be degrees F or C? What sensor are you using to get temperature?
Simple On/Off is what I am seeing but how well it works will depend on how well the heaters are controlled because depending on your application turning a heater Off at 26 degrees C or F the temp is likely to creep above that set point after the heating source (element) is turned off. Anyway you may have some considerations to make.
