Love-O-Meter project. Using temperature to turn on LED's

The Love-O-Meter project uses the temperature sensor and some code to turn on LED's based on how hot the sensor is. The LED's were connected to the 2 - 4 pins, and were hooked up to the sensor and made HIGH or LOW based on the "baselineTemp" of the surrounding air. As you can see in the GIF above, when my finger is away from the sensor, the temperature read is low, so the lights go down, but residually as the surrounding temp needs time to cool down. But when I put the my finger by the sensor, it goes up gradually by the same effect. I can speed up the LED's turning by touching the sensor with my finger, at which would make the sensor read my finger temp rather than the air temp, super speeding up the LED light process. The code reads the temp from the pin, and uses if, else if, and else statements in the loop function to continuesly read the temperature from the sensor. This then updates the LED's, as based on the temperature it will turn their levels to eit...
