Hi,
im trying to create a touch sensitive switch for my University project, but im not that great at electronics. i have found a diagram of one that i would like to use, but have become stuck as i was told that i needed a buffer? more specific i needed to pass the output of the 4049 to an amplifier as the output of the 4049 cannot be connected to any LED's? sadly this does not mean much to me. what amplifier should i use, and how would i connect it??any advice would be greatly appreciated. and im trying to do it so that one touch of the pad turns the lights on, and then touch it again to turn it off. im going to be using a 12V power supply.
the diagram is hopefully attached. also which is positive and negative?? im guessing the top is +ve and the bottom -ve? if somebody could complete the rest of the diagram for me, or help me to do so that would be fantastic!
many thanks
