Steps
. Collect LEDs
Collect your 10 LEDs. You can use any color LEDs that you would like. One common arrangement is LEDs 1-7: green, LEDs 8-9: yellow, LED 10: red. I used just red LEDs.
. Insert LED1
Insert the first LED as shown. The positive leg of the LED (the long leg) connects to the red wire. The short leg goes to the LM3916 IC.
. Insert LED2
Insert the second LED. The long, positive leg goes connects to the +9V rail on the far right side of the bread board. All of the following LEDs also have their long, positive legs connected to this rail.
