| 1. Prepare the Tools, SolderlessBreadboard and Spare parts |
|
| 2. Arrange spare parts position on the SolderlessBreadboard (i.e IC). |

SolderlessBreadboard:
The SolderlessBreadboard have many holes that user can plug the spare parts PIN into the hole, on the board, the 5 holes as a set mark as ABCDE, FGHIJ..etc. in vertical direction, so the electric current will also pass from A row to E row in vertical direction, but won't pass from ABCDE set to FGHIJ set.
|
The + & - 5 holes as a set, electric current will pass in horizontal direction, won't pass in vertical direction from + to – also won't pass to ABCED, FGHIJ set.

4. IC connect to the socket or IC connected |
Use A type resistan, they all have same circle on the left side, the circle is stand for below photo shows it's A type resistan on the circuit diagram. |
| 5. Connecting rest of resistances, wire with switch and LED |
| 6. Complete the SolderlessBreadboard for I/O port 300 / 301 experiment
