Any advice appreciated.
As a novice I can't work out why these errors come up when I try to verify the sketch downloaded form the page linked above:
sketch_jan23capsense:13: error: 'CapacitiveSensor' does not name a type
sketch_jan23capsense:14: error: 'CapacitiveSensor' does not name a type
sketch_jan23capsense:15: error: 'CapacitiveSensor' does not name a type
sketch_jan23capsense.ino: In function 'void setup()':
sketch_jan23capsense:20: error: 'cs_4_2' was not declared in this scope
sketch_jan23capsense.ino: In function 'void loop()':
I am using a macbook with 10.9.1, other sketches work fine, and I have reverted to earlier firmware to ensure sketches upload OK.

i am Having the same problem extracted the capacitiveSensor.zip file into the libraries folder where my sketches are but getting error messages
can anyone help please
Hi Paul i just wondered if anyone could help with the capsense issue i and a few more are having
this is the code and errors thank you

hi thanks for that well can you or anyone tell me where i am going wrong please i restarted the ide and followed someone elses advice and unzipped the files into Arduino / libraries but still no joy if anyone can help id really appreciate it thanks.
You should have a libraries folder in the folder where you store your sketches. If not, create one.
Open the zip file. There is a single folder in it. Open that folder. It contains two more folders. Drag the CapacitiveSensor folder to the libraries folder in your sketch folder.
In my case, that results in C:\Users\PaulS\Arduino\libraries\CapacitiveSensor containing CapacitiveSensor.h, CapacitiveSensor .cpp, keywords.txt, a Readme file, and an examples folder.
