My first post. So please be gentle. :)
I am trying to multiplex two OLED I2C displays on an Uno. I'm running a 4053 chip to switch the SCL and SDA lines between the two displays.
Litterally my code is: Set digital pin Low,( to change the switch on the 4053 ) write and display to selected screen (1). Set digital pin High ( to change the switch on the 4053 ) write and display to selected screen (2).
However, I suspect I'm missing some additional hardware somewhere in the way of resistors perhaps. My reasoning being that Screen1 seems to always work. But when interrupting some of the wires, screen2 jumps to into life. But it doesn't do it all the time. So I'm guessing perhaps something is floating somewhere.
Any help would be appreciated as I'm from a programming background rather than an electronics background.
I can provide details of the circuit if necessary.
