you say you are not an electronics expert;
but you are going to remain there if you do not experiment . its acuallty pretty easy to understand .
all you need to know is the working of a transistor, and a dpdt relay.

just 'forget it'?

there is absolutely NO way i can use the tiny lens to stream to audio vieo?

ya, use a mosfet. it will allow you to speed control in any ONE direction.
if you want to go in both directions, use a DPDT relay.

in this , they have used a TIP 122, u can use this or even a mosfet.

i had purchased a small cheap spy camera.
its pretty small(around the size of one's thumb ).
whenever i press the rec button, it records the video & audio, and store it in an onboard memory card.

after opening up the camera:
i can see a black and red wire coming from the lens,which is probably the wire.
and many other wires,(around 10) coming from the lens, which is probably going to interface with the card .  

now, how do  i connect the camera, such that it transmits the video to my tv (audio video cable).

but what logic to use to distinguish between sounds?

please show me the breadboard view of the schematic with the ca3140 .
also, wont a simple transistor work?

i researched google quite a bit to get something to amplify the signals of a mic.
i have been thinking, what is the problem of using an op amp?
wont that work?

but wont i have to be whistling REALLY hard to get this working?

hi,

i am trying to program a car, that will stop if i whisle to it.


is it possible to detect a whistle without using something complex like bitvoicer or easy VR?

something like understanding what a whistle wave looks like, and then comparing?

the input will obviously be thorugh an ordinary mic.

that doesnt solve my problems(i had already seen those )

i would rather if someone explained me the solution .link provided dont really help as much as explanations do

i am trying to get the futaba s3003 to work
it moves all fine , but when i use myservo.write, it starts moving about a point for a point, befor coming to a stop.

(something like a pendulum)

what am i doing wrong?

of course it can

but, is that feesable enough to?

the old ping is not accurate

this newPing is pretty cool
i would love it if there was a way to run the newPing library

i am using HC sr04 distance sensor
with the newPing library

the problem is

when i use new ping library , i am not able to use the tone functions

core.a(Tone.cpp.o): In function `__vector_7':
C:\Users\Harsh's\Desktop\arduino-1.0.3\hardware\arduino\cores\arduino/Tone.cpp:535: multiple definition of `__vector_7'
NewPing\NewPing.cpp.o:C:\Users\Harsh's\Desktop\arduino-1.0.3\libraries\NewPing/NewPing.cpp:214: first defined here

also when i use lcd.write(from the liquidcrystal library), i have to typecaste the value of a custom created byte .


any suggestions to how to solve this problem?
