Speed controller from input

[giannaras13]

Hello, i need to do a board that will do those things 1)receive speed measured by a servo 2) to make maths for example (servo speed / 6 ) and the result to be the speed of an other electric motor

Like this Servo speed ( 300 rpm ) --- > servo speed / 6 = 50 rpm ---> control 12 v dc motor with speed of 50 rpm

Can you give me any ideas? Is it possible to use arduino,but will it receive as input the servo speed or it need convertion to 5v pulses?

please help me i'm newbie :evil: :-D

You should use something like encoder and you can use stm8s discovery kit which is really cheap eval board it has a lots of example. On the other hand TI launchpad msp430 based eval board is capable to do it.
