Yesterday i built something like a giant spdt switch with an 330uF condensator and 12v relay, it also has an 12v pover input. The switch has 3 positions down, middle, and up. When i move the switch to the down or up position, it should send an impulse to my keyboard card which should emulate the G key on the keyboard.
Now wanna add 6ledsto the circuit 3red and 3green. When i move the switch to the down position, then red leds should lit up for 12 seconds and then should green leds stay lit until i move the lever to the up position. When i move it to up position, then the green leds should turn off and the red leds should lit up for 12 seconds.
