    moving two wheels of robotic car at a same speed ??

    the problem seems to be moinor but i personally feel it is a major problem , i designed a car with 2 back wheels n 2 front wheels , back 2 wheels are controlled by two motors , due to some mechanical error my right back wheel is little um-smoother than my back left wheel i find torque difference...

    voltage control oscillation--help me

    1)why we use divided by counter or sth for frquency synthesizer (pll) ...i guess it would be better if we change Vco (input for voltage control oscillation) n watch the output of frequency in digital oscilloscope ...isnt tht easy n fast ....n other question too ..i am a begineer of electronics...

    how to use 555 timmer ic??

    the answers for ur question are infinite shashir ...the only thing it matters is how will its output signal (square pulse) helps in our ciruit design ....like it helps in binary countnig (1 of the big achievment in digital) , shift register , circuit whose on time is some interval of time...

    How do solar cell and module work?

    i am sure they work in phtoelectric effect ....they use rechargable batteries which get recharge by the electron ejected or generated thru photoelectric effect ....so tht we can get required charge n voltage ...the element whose ionihizing energy is minimum are use for this purpose .....dunno...
