Soldering The Component

Objective:

1. To fix all component
2. To make a solar regulator function
3. To make a troubleshoot after finish all procedure

Procedure:

1. All component that use ensured function before soldering.
2. Punch holes in the circuit so that the component can be matched
3. Right match all component to the circuit following the schematic to the each holes that make.
4. Prepare the tools needed to make the solder such as solder, lead solder, lead sucker, knife, and also multimeter 
5. Enter into all the components to the holes of each component.
6. Before soldering the components, make sure the terminal and polarity in proper condition
7. Soldering all the components one by one. 
8. Make sure each component is connected to the circuit
9. Because the circuit has a close position make sure the connection of the components in short circuit
10. Use multimeter to make a testing
11. If there occur short circuit, broke and check again by using multimeter
12. Solder the solar panel 7 volt
13. Before that check the voltage input from solar panel.
14. Lastly solder the solar panel
15. Check the input voltage from the solar panel. Before that put the solar sun light
    
16. Check the voltage at variable resistor.
17. Check to the output voltage

•  Result:

Input Voltage : 6.1 volt
Voltage at Variable Resistor : 4.84 volt
Voltage Output : 1.76 volt
 
Analysis:

From the output value we know that there have a problem output voltage. The variable resistor has been set to the maximum angle. And the output value also shown the same value. Know the common problem is the output value.

Conclusion:
  
All connection of component must be check. The polarity of each component also must be unsure. The voltage of each component must be check
