Input Devices ====================== This week I will use analog sensors to measure things like temperature and light using a Peizo vibration sensor and a phototransistor. For reference, I used the Arduino love-o-meter project as it used the temperature sensor. I started by collecting all the components.  I used this schematic to connect everything.  The circuit setup was fairly easy. This is how it looks.  At first all lights were continuously on. I checked the serial monitor and saw that the temperature was around 26 degrees without touching. So I adjusted the baseline temperature to 25 in the sketch. After some trial and error, I adjusted the sketch so that on touching it lightly for about 5 seconds, the second led lit up and on holding it tight for some seconds the third led lit up. The serial monitor indicated temperature range from 26-32 degrees. So an increment of 2-4-6 degrees worked out perfectly.  This is it in action.  ####Code  ####Tutorials [Arduino Project 3](https://create.arduino.cc/projecthub/godboi123/love-o-meter-bda552)
