I wan't to build a diversity controller similar to this one.
A diversity controller is basically a circuit which detects the strongest RSSI Signal of multiple receivers and provides the data signal of that (the strongest) receiver.
As a receiver I use boscam RX5808 receivers.
This receiver can be switchen between 8 channals through a 3 bit output interface. The CH1-3 outputs are active high 5V which got to be pulled to ground.
Is it possible to put these receiver-outputs on an arduino digital inputs, to either put them on ground or not?
How exactly do I implement this in software?
