Evening all, I've had a look through old threads but can't find an answer to this.
I'm working on a project (a Solar tracker) and have three comparators (one and a half LM393s - the outputs of which will ultimately drive PNPs, then 555 delays to two relays to drive a motor).
My question is can I feed the outputs of two of the LM393s (via a 1K resistor each) to the base of one transistor (probably will be TIP126), so that it will turn on if either of the 393s go low, or do I have to have a separate transistor per comparator?
Any help appreciated!
