LED project fablab india
led lamp are connected in two type's
1) 24 LED connected in series form.
2) 24 LED connected in parallel form.

*24 LED connected in series form
The one LED required 4volt.max imam and 3 LED connected in series that way total voltage is given by .
V=L1+L2+L3 Where L1 is required 4 Volt.
=4+4+4
V=12
The 3 LED connected series form and required 3 Volt.When Voltage is applied to the across the lead of the LED,and the current start to flow.
LED bulb calculated power
input voltage V=12Volt.
current I=200MA.
calculated power P=VI.
P=12V*200MA
P=2.4W

Feature
1.It has low cost .
2.Has durability one years.
3.It has required minimum power.

24 LED connected in parallel form.

It has operated 4.5V,to give the 4.5V in connected in parallel form LED,but has required some more power.
LED bulb calculated power
input voltage V=4.5Volt.
current I=600MA.
calculated power P=VI.
P=4.5V*600MA
P=2.7W

Feature
1.It's required minimum voltage
2.It has low cost .
3.Has durability one years.
4.It has required minimum power.

Milk tester ­

Milk tester is a novel project of fablab India. This tester can sense the changes in milk by step impulse responce . The research and development in project till today can identify different fluids but still some work needs to be done to sense changes in milk as it is in development stage.We are taking the readings for it.
