I am pretty new to electronics, and arduino so I am not sure what i am doing wrong. I have an arduino uno that i am trying to make a touch sensor for my under cabinet lighting for my new kitchen cabinets. I had a guy write the code for me, everything works great until i plug in the ballast and then i can not get the arduino to register my touches. It will work if i touch the ground on the arduino board and tap the sensor but if i am not holding it i get nothing. The ballast i am using is a meanwell lpf 16d-24. Can anyone point me in the right direction to get this working? thanks!
