basically, im trying to create a circuit that uses a 555 oscillating circuit that will be able to give a range of frequencies - by using different resistor values in the potential divider to change the input at pin 7, each triggered by a switch of some sort.. but im stuck at how to only allow one resistors value at a time. btw, this is for an audio type project.
i presume their will be a way of using logic for this, but we havent really been taught enough for me to work it out
any advice would be appreciated, even if its 'your doing everything wrong'!.
