Hi All,
I am working with very limited space in the controller I've made; yet I need to change the input voltage at a remote mini USB connector coming from the computer. There's no room for an additional circuit board and the voltage has to be changed at this location. My plan is to wire in a 2 resistor (1k,2k) voltage divider at the connector. There are 2 10k pots on 2 analog in pins and up to 25 digital (pullup) switch pins. The 2 pots will always be in play, but at most maybe 5 or 6 buttons will be in a closed state at any given time. Will I have enough juice for everything to work?
Thanks
John
