INTRODUCTION

As i got a plenty of time left before final week, i did some testing of my project to the application. Here i would to get the real result; my project can be proceed or not. In my magazine, the application use for car, but i tried to use a bike as a subject

TESTING AND APPLIED

Before i connecting the project input with the wiring bike system, i did a measurement about the current and the voltage first. The result of measurement get a little higher than the expected was. The current increase rapidly during i ramp the fuel and the voltage increase too. This already explained by Ohm's theory

V=IR

But inside my project circuit, the fuse is inserted as the safety one as to cut off the if current reach maximum where will burn IC

here some picture during i testing the prototype

bike light wiring system

the measurement is taken by using multimeter

read multimeter value

connecting the light system with alligator clipper

wiring is system is connected with the project

Project is testing

RESULT

bellow is the result after i did the experiment

Explanation 

first condition:

for the real application, during driving a car, when the light intensity fall (like sunset condition ) to a certain level the system is automatic on, but the system is off if the light intensity not changed even at night if the car surrounded by light. The system is depend on the light intensity only.




second condition:

During in the middle of driving when a car facing with other car, monostabe start to on for certain seconds (can be adjustable) as the comparator is off ( voltage V1 > V2 at op.amp ). this will prevent the light system to turn off



third condition

When driving a car to the parking area, there were a lot of light (lamps) the  light system from on turn to off as surrounded by brightness of the lamp at there. This because the duration of monostable only for certain period only, not for long period ( minutes). The light system will active back if the car going out from  that parking area. This situation for night (darkness condition only).
