Buy
The Component
Objective:
1. To search
all the components and material use for project
2. Purchasing
all the material
3. To
recognize all the material that use in the project
4. Recognize
the components codes
Procedure:
1. List all
of solar power supply component before purchase
2. Confirm
every unit all of component
3. 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

Conclusion:
• After finish this week of activities,
we are able to understand how to read all components’ code for constructing the
circuit in the right way.
