Post 3- This is going further on to use other devices like relays ( I think most of you wont have this with you )
,transistors. Okhay. Mostly we need the above mentioned ones to USE DEVICES THAT REQUIRE A HIGH current flow.
I might have mentioned earlier that an arduino can only take up current to a maximum of 250ma (MAX) .Which is NOT enough
to power a MOTOR, ( Be it any motor)
Okhay , Heres the deal, IF any one bricks their ARDUINO. [Its not my fault], get a warranty and Use appropriate
devices and transistors for the same.As most of you have different power requirements.
So, what we use here, IS a transistors or power transistors.
As you all know the working of transistor as switch. Connect the BASE to the GPIO and THE VCC along E to C .
Basically, Thats how its done. So, what does that make of this. Okhay, Whenever we give a high to the base,
there will reach a threshold and the C-E current flow occurs. More can looked upon in GOOGLE >.< .
So, we have thus made a "digital SWITCH"
I have already EXPLAINED HOW TO USE RESISTORS AND STUFF IN AN ARDUINO.
Try to accomplish a working digital SWITCH version of a motor you people have connect it to a
Q) Make a Digital OHMmeter. Device a Circuit. To measure any resitance of various objects between two wires.
Print the resistance on the Serial Monitor. DO the MATH according to your ow
n CIRCUITARY.
