Hey all, quick question. I want to control some LEDs with push button switches but don't want to allow both sets to be on at once. Seems simple enough... I just connected each wire to a transistor as per the diagram so that whenever one switch is pressed, the other switch grounds the circuit.
The problem I'm having is that my LEDs can only handle so much current and I'm having difficulty determining how much current is being diverted by my transistors. If for instance switch 1 is pressed, I assume that transistor 1's base has 0.7 volts applied to it but how much current does that translate to in this state?
Thanks for the help.
