Step 3Wires for leds (optional)
You can do like what I did for the LEDs or do them like the diodes in Steep 4 if you want to do a bar graph.
I added a wire to each position (7-12) Then did the diodes type1N5817 Schottky diodes on a PC board.
I will show how to do the LEDs later on another Instructable.
