I am building an led fade in / out circuit. It fades in when powered and out when the power is removed. I have found a circuit on the www but the website chap hasn't been so forthcoming with more information. I don't currently have a bottomless reserve of varying resistors and capacitors to help find out what I need to change the time taken to fade. I have been told to replace the 100k resistors and 100u capacitor but haven't been told to what. The circuit I am building is exactly as shown in the attachment. I don't know what the rate is either for the given values shown but from a whole days research am guessing its only a few seconds. Also from what I have found out on similar circuits that its only the capacitor and the resistor (shown to the right of it, I believe this is generally known as the draw down) that should be changed. Inevitably I will build the circuit and end up experimenting but would appreciate it if I could get a better idea of where I should be going with the values.
Thanks in advance.
Thanks in advance.
