With minimal electronics knowledge, I'm trying to make a circuit using 2 bicolor LED (red 2.0V, green 3.0v, common anode), a 3v battery (CR 1220 lithium), a couple of reed switches and a toggle switch to power the circuit off and on. It involves a 180 degree swinging door with reed switch magnets mounted on it.
When the door is opened to either side, the bicolor LED on that side is green and the LED on the other side is red and visa versa.
When the magnets are not near either reed switch, both red leds are lit. I can't get the green led to light. I figured the 3v battery couldn't handle the draw for the red and green LEDs to be lit at the same time because the green LED is rated at 3v and the red is rated at 2v. So I put another 3v battery in series with the first battery. Still wouldn't light the green LED. I then added a 430 ohm resistor included with the LEDs, to the + pole of the battery. Didn't help.
I know I could split the circuit in two, with a 3v battery for each side and use a DPST switch to toggle power for both circuits, but was just wondering if there was a simple solution to keep it as one circuit. Sorry about the non-technical drawing, hope it conveys the basic idea.
