I buillt this dog whistle,I replaced the potentiometer with 4 momentary switches inline with a resistor. (each button has a different resistance on it, thereby creating a different tone) they are connected with a common to the trigger/threshold pins on the 555 timer
when I powered on the timer and pressed a button I am getting the same tone, regardless of the button pressed. is there a way to make it so that each button isolates the other resistors (i think that since they all share the common that I am getting all the resistors to working together)
Is this possible with the 555 timer or do I have to use another IC?
