- mobile controlled car
Every key in our keypad of mobile(0-9 including * and #) will have one min and one max frequency .so every key will have it's own uniqueness.
MT8870/HT1970 any of these two ics are used to decode this frequencies .
a corresponding responce of this inputt will be observed at pin 11 to pin 14 of this ics
(for more information just google for mt8870 pin description)
the outputs from mt8870 are connected to the not gate which will inverse the logics(1 to 0 and 0 to 1) these logics are give to arduino (here 1'm using arduino duemilanove 328)
u are free to use any arduino and atmega 16A also preferable
program is written in such a way that
when key 2 is pressed the two motors connected to l293d(motor driver ic) should rotate clockwise
when key 8 is pressed two motors rotates anticlockwise,
when key 4 is pressed motor 1 clockwise motor 2 anticlockwise,
when key 6 is pressed motor 1 anticlockwise motor 2 clockwise.

- vu meter (volume unit)
i hope this project will be liked by music lovers
coming to electronics view of this project , it can be made by either using any op-amps or transistors. here i'm making this vu meter with the transistors
some other applications: it can be used to find the charged amount of any battery
will be updated soon!!!
- wireless mobile charger
it based on mutual induction between receiver coil and transmitter coil .
