 Projects using the DHT22 Temperature/Humidity sensor with Arduino Uno
+
+I'm adding my code to the project specifically for: 
+Using the ASAIR AM2302 (DHT22) Temp/Humidity sensor with a Velleman VMA412 2.8" 240x320 resistive touch screen
+Draws a thermometer bulb graphic with two buttons for you to choose to display the temperature in
+degree Celsius or Fahrenheit and shows humidity on an analog meter needle display.
+
+Turns out that I had to make a lot of changes to the sketch made by GadgetReboot to make it usable on my display
+the only thing that I have in common is that analog pin 5 isn't used on my shield also, changing it to a digital pin number 19
+makes it usable for the sensor... However that's about it, my calibration is completely different in pin usage, the most outer
+touch values and usable pixels.
+Therefore I had to rewrite pretty much the whole sketch because for me it's completely unusable as is.
+It's not perfect yet but at least I managed to get the proportions better so now it starts to fit on the screen, 
+I still need to figure out a couple things because I don't really know what I'm doing so I have to learn by changing one thing, 
+then upload the sketch to see what changed which is a lot of work and takes a long time but my added sketch will be usable for 
+anyone with a similar display that I'm using.
