Breadboard
• Wires and Components pushed into holes; Holes interconnected with metallic strips
• No soldering required
• Advantages: Handy, Saves Time & Money, Reusable, Easy Troubleshooting
• Disadvantages: Not suitable for complex circuits
• Rows (2 in first half and 2 in second half)
• Columns (36 in upper half and 36 in lower half)
About Breadboard (BB)
Board to PrototypeCircuits
Think of BB into 3 sections
Section 1
Section 2
Section 3
Combining all 3 sections
BB Drawing
Providing supply to BB
• In 1st Row: First 25 holes get Vcc (positive)
• In 2nd Row: First 25 holes get grounded (negative)
Connecting two halves of BB
• To connect first set of 25 holes to the next set of 25 holes, run a wire from the 1st half to the 2nd half of bb
• In 1st Row: Now all 50 holes receive Vcc (positive)
Providing Vcc to any column
• Run a red wire from the first row (any hole) to any column
• Red wire: Transfers Vcc from the 1st row to the corresponding column
Connecting two columns
• To connect two columns, run a wire from the 1st one to the other
Connecting LED on BB
• Wrong Way: Don’t insert both legs of LED in the same column
• Correct Way: Insert two legs of LED in two different columns
Connecting Resistor on BB
• Wrong Way: Don’t insert both legs of resistor in the same column
• Right Way: Insert two legs of resistor in two different columns
