Hi, my first post here hope someone can help me out..
The circuit is simple: a touch connection current being amplified by a transistor to drive an LED.
I would like to have multiple independant touch controlled LED circuits (resistive not capacitive touch switches) Ie. two touch plates per LED, where the amount of pressure placed on the plates varies the brightness of the LED.
When there are two of these, such as in "Touch LED Circuit 1.jpg", the problem becomes that the two LED's can't be operated independantly of each other. (Because of the body being a common point).
Can remedy this by using two voltage sources, as in "Touch LED Circuit 2.jpg", but this seems like overkill, as I eventually wish to have about 10 of these LEDs.
So is it possible to use one voltage source and somehow make those currents independant when more than one touch switch is closed?
