I breadboarded a bit switch tonight with a DIP 8 pin variety of the PIC, and it seems to work well. I am easily able to turn of a set of LED's with a switch on the radio.
I ripped apart one of my kids broken Fairy Wands from Disneyland to convert it into a fancy LED light show on one of my RC aircraft. The PCB with a small IC that is controlling the LED flashing pattern has a tiny push button that shorts a 3v output to ground, and by doing so, it alternates the pattern of LED blinking.
I plan on hooking up the LED's directly to 5 volt output from a BEC, but would like to be able to switch (short) the two wires that go to the little button while flying.
Could the bit switch be used to do this? If so, do you think it would be better to use a small solid state relay to do this? The current is VERY low. The Bit Switch can't drive a pin to ground selectively, can it?
