3 LEDs and 3 Switches..
Hi all.
Can anyone give me a diagram or help on how to do this.. I've got 3 LEDs, and 3 Momentry Switches. Id like to make it so that 1 LED is on at all times. eg. 123 - ABC Press 1 and A Lights, BC off. Press 2 and B Lights, AC off. Press 3 and C Lights, BC off. And so on. Defalut would be 1-A when inital power up is done. I could do this dead easily with small relays, but Im trying not to use them. Idealy it would use Transistors or a small chip. The source is +5V fed from a 7805 Im trying to get away from the old Clicking way of doing it. !! Any help on this would be very welcome. Here is what its for. http://www.youtube.com/watch?v=fT1mNeno8XY The 3 Large LEDs at the bottom center. Regards Wombat. |
