You will understand the fundamentals of LM35, its working and how tó interface LM35 with Arduino.Analog indicates the result voltage of LM35 is usually analog in character and linear means this output voltage varies Iinearly with the change in heat range.So we need to simply link the Analog pin of Arduino to Vout pin number of LM35.The only difference being in the range of temperature measurements.
![]() So 350 will refers to (51023) 65 and this will gives us the result voltage. Try to bring the warm iron close up to the surface area of LM35 and see the shift in temp. What this indicates is that mainly because shortly as the temperature rises to a particular worth DC electric motor will begin running. ![]() Similarly IN2, IN3, ánd IN4 for Out there2, Out there3, and OUT4 respectively. In our situation, the Vin flag of Arduino since we are usually going to use exterior 12 sixth is v adapter to energy Arduino. Then by using the formulation explained earlier convert this worth to degree Celsius. ![]() As you can discover temperature right now can be around 30 diploma Celsius which is less than 40 degree, Motor is usually not spinning.
