anyone know how to fire the switches on the CD4066BE with arduino.

should i connect an arduino digital pin to the control pin on the the CD4066BE?

maybe use a resistor with it?

sorry - probably a somewhat newbish question!  smiley-grin

Assuming that you have checked the datasheet... anyway, like any digital switches, the switch's state is controlled by a control pin. For instance, for channel A, asserting pin 13 to high will connect pin 1 and 2. So, basically, you can use Arduino's digital output pins to control the control pins of the switch.

Where? What are you doing?
Logic to logic connections do not need a resistor. So you can connect the arduino directly to the switch control pins.
