Breadboards
testing and experimenting with electronic circuits
Prototype circuits, test components and do not require any soldering

2. A Bread Board
Way easier than doing this. Before the 70’s, electronic enthusiasts used breadboards to do this - Circuits were often constructed by wire-wrapping components onto nails driven into flat pieces of wood like breadboards.

What is a breadboard?
a temporary circuit board for testing and prototyping circuits.
A plastic box full of metal strips, with a grid of holes on top

5. Inside a Breadboard
Bus strips: are used primarily for power supply connections
Terminals: will build your circuits on the terminal strips by inserting the leads of circuit
Trench: often referred to as ICs or, simply, chips, are manufactured specifically to fit onto breadboards.

6. Powering a Breadboard

7. Powering a Breadboard
Connecting the Ground (GND) pin from an Arduino to a row on a mini breadboard. Now any leg or wire connected to that row will also be connected to Ground.

11. Wiring a Breadboard
Always stand your components "Straight Up" if possible.
"Always" lay your Jumpers "FLAT" to the Breadboard.
Cut wires to the length.
For large circuits, make temporary labels with masking tape for each connection.
If it’s a large circuit, you can label your wires with masking tape for each connection.

12. Calculating the resistance
Resistors
Calculating the resistance

13. Identify the reading direction
Step 1:
Identify the reading direction
Silver or gold band always the last band

14. Step 2: Refer to color coded chart Identify First significant number
Second significant number
Multiplier
Make up a mnemonic to remember this

15. Write down the first and second significant numbers. (56)
Step 3:
Write down the first and second significant numbers. (56)
Multiply this number with the multiplier (100)
56*100=5600Ohms or 5.6kohms
Place the first and the second numbers beside each other and multiply by 100

16. The percentage by which the resistance varies from the stated value
Tolerance Band
The percentage by which the resistance varies from the stated value
5% of 5.6kohms
280
5320 or Ohms
percentage of error that the reistor has

17. Find the Resistance!
