Breadboard Setup and Voltage Supply:
# Connect the positive and negative rails running along the top and bottom of the breadboard. The positive rails have a red bar running next to them and are labelled with a "+", the negative rails have a blue bar running next to them and are labelled with a "--". Use a short red wire for to connect the positive rails and short black wire for to connect the negative (pic)rails. Make your wires long enough to avoid blocking any of the holes on the breadboard, but not so long that they are trailing off into space. See the picture below.

# Set up your multimeter: attach the red and black probes and remove the covers over the tips.
# Test the continuity settingof the multimeter. Turn the dial to the position in the photo below, and make sure the black probe is connected to the middle socket and the red probe is connected to the far right socket. Keeping the probes apart, the screen should display "1" on the far right. When you touch the two probes, it should beep. This setting lets you know if two points in a circuit are connected without power running through the circuit.

# Use the continuity setting on your multimeter to check the connectivity of that you successfully connected the positive and negative rails you just in step 1. Are your red supply holes connected. at every point on the board? How about the black ones? The multimeter should beep if it This makes sure that your power is connecteddistributed properly for later use.

# Clip the end of the power adapter off, saving enough wire with the plug to reconnect the two later in the semester (do not clip the wires too close to the plug).
