FYP II

Week 11

Title: testing the LDR and  DC motor performance

Objective: Testing the LDR performance and motor movement

Content/Procedure: LDR performance is testing by adjusting the variable resistor.The reading value of LDR is is take in two position (when LDR  is on the light and when LDR is on the shade)

and observe the DC motor movement. 

Result :

FIXED RESISTOR	Vout (LDR on light)		Vout (LDR on shade)	Voltage Change (V)
15k 3.2k	9.28               8.9		8.19 8.19	0.99 3.24
2k	8.88		5.66	3.48
1k	8.16	5.4		4.25
500	7.14	3.87		4.74
300	6.55	2.4		5.21
200	4.13	1.34		3.2
100	3.34	0.9		2.78

CONDITION	MOTOR DIRECTION
LDR1> LDR2	LEFT
LDR1< LDR2	RIGHT
LDR1= LDR2	STATIC
LDR1> LDR2	RIGHT
LDR1<LDR2	LEFT

Week 9

Title: welding the hardware design

Objective: To make sure the hardware part is build/ welding according to the design.

Content/Procedure: the metal/rod and some of screw is use for this part. the DC motor is welding attach to this design. i use black colour to paint this hard ware.

Result & Analysis:

Conclusion: the hardware is function completely according to the design

WEEK 8 :SOLAR TRACKER HARDWARE DESIGN

Week 8

Title: Proposed the Solar tracker hardware design

Objective: To ensure the solar tracker can stand any weight that will be use

Content/Procedure:

The design being made using scatch up 2010 tool to get the idea on how the hardware will be present on the Industry Day. So here I enclosed the design for solar tracker to proposed the project advisor for further information.

Result & Analysis:

Proposed Design Model for Solar Tracker

Figure 1: top view

Figure 2 : overall design

Conclusion:

The design of the hardware of solar tracker well accepted and done.

WEEK 7 : COMBINING CIRCUIT

Week 7

Title: Wiring the separated circuit 

Objective: To connect the LDR circuit to Relay circuit and magnetic sensor.

Result & Analysis:

this is the sketch of the circuit connection

me testing the circuit

in this picture, i am using switch to test the separated circuit and change to magnetic contact sensor after that
