Hi all,
I am building an alarm clock that will be driven by several PICs and displayed on an LED display. One of my displays requires a fair bit of power (15V and way more AMPS then a PIC can handle) The segments become "light" when the SegmentPIN is set to low. I will have all my digits tied to +15v and i will control each segment individually rather than multiplexing (only 4 digits). Heres my question...
Will i kill my PIC by doing this?
When the segment is light, the PIC will see 0 volts
When the segment is off, the PIC will output 5V
Thanks for the input!
