Objective:
- To search all the components and material use for project
- Purchasing all the material
- To recognize all the material that use in the project
- Recognize the components codes
Procedure:
- List all of solar power supply component before purchase
- Confirm every unit all of component
- Do survey for price to the store and also from the internet.
Result and analysis:
- All the component are purchased
- The reason for why we have to recognize the codes of the component is to have a right component to construct the circuit
