transistor Transistor as a heater device and measured by lm35LM35 temperature sensor?

theThe aim is to make tempa temperature control circuit using arduino unoan Arduino Uno as a controller  , lm35an LM35 sensor as feedback to measure the actual temptemperature, a TIP31cTIP31C transistor as actuator to control the power disspateddissipated (heat).and i) I have a 12V,1A power supply 12v,1a . note

Note: theThe transistor and sensor are near to each other  .

iI know that arduino unothe Arduino Uno should send pwmPWM through a resistor to the base of transistor . but, but what about collector and emitter  ? should i

Should I put 12v12V to the collector and gndground to the emitter  ? butBut that would mean a short circuit .

thank u .
