Several capasitive sensors on Arduino UNO?

Hi! I am new in this.

Can I use several capasitive sensors on my Arduino UNO board?

I tried the code below but it doesent work. Any ideas?

"CapacitiveSensor capSensor = CapacitiveSensor(13,12);

CapacitiveSensor capSensorB = CapacitiveSensor(4,2);"

The demo sketch on this page shows multiple (3) sensors so it should work with more than one. I did notice that all sensors share a common pin. Not sure if this is a prerequisite or just frugal use of pins.

Thnx! I found code for table piano wid capacitive sensors, that might work!
