    im doing a project in logic. and it is all about sensing the temperature and when the temperature increases.. a dc fan also increases in speed... i already have the circuit in the input part.. what i need to know now is the circuit in the output part.. and also how to make a code in variably increasing/decreasing the speed of the fan.. im using a 12v dc fan..

    please help me.. just some knowledge.. :)
