WEEK 12 (SEMESTER  2)

Date: 30.11.2015
Tittle: Complete and combine the wiring in this project

Content:For the last week,I had complete the wiring in at the fan and motor.I  am also done with the wiring at thearduino.Below is the picture of the wiring:

WEEK 11 (SEMESTER  2)

Date: 23.11.2015
Tittle: Function of voltage divider and  wiring
Content:In this project, there number of voltage divider used is two. The function of this voltage divider is to measure the value of the input voltage and send the result to the Arduino. The first voltage divider is to measure the output from the power supply and the second voltage divider is to measure the output from the generator. Below is the example of the voltage divider.


Here is my connection of half full circuit operation



  Here is another half full circuit  on my wiring at the fan motor

WEEK 10 (SEMESTER  2)

Date: 11.11.2015
Tittle: Coupling method between Two Dc motor
Content:The reason to use of this method is to get the higher output voltage from the generator. From the experiment done, the percentage of the output voltage after apply of this method is increasing until 100%  from its original output voltage.

The connection between the two fans is in series so that the fan can take more voltage due to the motor of the fan will spin faster than either of the original motors. The weakness of using this series method is the torque. Therefore, the suitable type of fan is important to less the torque. If the fan is connected in parallel, the result is the fan motor will deliver more torque than its original motor and the weakness is the speed of the fan motor is limited. Below is the way on how to couple the two fan motor.


The precaution that needed during the coupling process is the nut should screw up tightly so that the motor will operating more efficient.The position must be really in series in order the motor  to function correctly.

WEEK 9 (SEMESTER  2)

Date: 5.11.2015
Tittle: Modification of the fan


Content:The fan is modified by adding the Dc motor of 3 Volt.This is one of the method to increase the output voltage from the generator.The result of the maximum output from generator after applying this method is 3.6Volt.Here is the picture after the fan is already modified:
