1. Breadboard
Power bus + (red) and – (blue) on left and right of breadboard
abcde (green) are all connected in a row
fghij (yellow) are all connected in a row
abcde and fghij are not connected.
If you want them connected use a jumper
Use caution inserting components in the breadboard. Hold ends of leads so they do not bend when inserting 1
Two wires inserted in the same row are electrically connected
Two wires are in different rows they are not connected
Two wires are connected across the center are not connected 2 3

2. Series Components in a Circuit (Head to Tail)2
Connect the voltage source positive connector to the + bus
Add a jumper from the + bus to the row for the first component
Insert the first component so one end is in the same row as the jumper
Insert the second component in row ending the first component (tail to head)
Jumper the row ending the second component to the – bus
Connect the voltage source negative connector to the – bus
Turn on voltage source - circuit is complete to energize circuit 3 4 5 1 6

3. Parallel Components (Head to Head)
Connect the voltage source positive connector to the + bus
Add a jumper from the + bus to the row for the first component
Insert the first component so one end is in the same row as the jumper
Insert the second component in same row with the first component
Jumper the row ending the second component to the – bus
Complete the circuit by connecting the voltage source negative connector to the – bus
Turn on voltage source when circuit is complete to energize circuit 2 3 4 5 1 6

4. Use DVM to measure Voltage or Ohms1
Connect the probe (red) to the breadboard start row of the component to be measured
Use a jumper if the probe does not fit in the breadboard
Connect the other probe (black) to the breadboard end row to be measured
Set the digital volt meter to measure volts DC
Use this setup to measure resistance. Set the multi-meter to measure Ohms.
Note: you can never measure resistance when the circuit is energized 2 5 4 3

5. Use DVM to measure Current
Multi-meter must be inserted in series in the circuit to measure current
Move the probe to the mA connector
Remove the jumper connection from the voltage source negative connection
Connect the probe to the – bus on the breadboard (Tip: you may need to use jumpers if the probe does not fit n the breadboard)
Connect the common probe to the voltage source negative connection
Set the meter to measure mA DC (mode button if necessary) 1 5 3 4 2
