I'm new to arduino but I decided its time to jump in and start my first real project. Eventually I'm going to want to incorporate cap sensors into this project so I figured it wasn't a bad place to start. I was able to find the cap sense library here:
I can see on the serial monitor that the switches are being properly recognized but when I try to use the data to light an LED it is very dim. If I drive the LED instead with an npn transistor I get the brightness I want. I therefore assume that my Arduino doesn't have the driving capability to use the cap sensors and light an LED at the same time. Is this something I'm going to have to accept and add the transistor circuit or am I missing something? I realize its not a big deal to add a transistor but I figured I might be able to learn something by asking. Thanks!
