There are 2 values you might need to change in this code, and the sample button code. First, the val0high = 350; should be changed to approximately the highest value that your sensor puts out on the serial monitor when it is touched. So, run the code, open the monitor, wait for it to register the sensor, (a few seconds) and then touch the sensor. Note the highest number and use that value. For the leaf I used it was 350.

Secondly, threshold = 10; can be modified. This is the number that your sensor must sense above, for it to trigger a reaction. If your sensor is jumping a little around the lower numbers, you might want to make this a little higher value. However, if your sensor is consistently at 0 when it is waiting for touch, then you can safely lower this if you wanted to. Think of this value as the sensitivity.
