Keep a Light On

Here in Step 3 Ruth and I had to use a Bread board to keep on a light bulb. First we unplugged our Arduino that was already plugged in. We then took one end of a black jumper wire and plugged it into the GND slot on the right side of the Arduino. Any hole in the column worked. Next we connected the other end of the black jumper wire to the ground rail on the right-hand side of the breadboard (the ground rail is the last column under the minus sign). We had to take one end of a red jumper wire and plug it into a Pin on the Arduino. Any would work as well. Again we connected the other end of the jumper wire and plug it into a Column on a row on the breadboard. Any Column A to D worked. We left leave E open for the transistor. Then we took one end of a resistor and plug it into a column E in the same row on the left side of the breadboard. Once more we connected the other end of the resistor into Column F, same row on the right side of the breadboard. Again we had to take the positive end of a red LED (the longer leg) and plug it into the same row. Lastly we connected the other end of the LED (the shorter leg) to the ground rail on the right side of the breadboard. This was all completed and we were able to witness the light stay on.
