[Mini Project] Controlling the temperature of a closed environment (Log 2)

In the previous post I had posted that based on requirement by user that is for either heating or cooling we can switch on/off the heating and cooling element, but this approach seems naive for purpose of achieving a range of temperatures. So we decided on using a peltier element for heating as well...
