i'm planning to make a prototype first... dc motor might do the job... what circuit should i place after the output of the if sensor?... so that the motor will turn clockwise and anti-clockwise at a certain interval of time in order for the door to open and close... if u may i would ask a copy...
can someone help me with my project... my project applies the function of a ir active sensor connected to a motor... when a preson passes through the ir sensor it automaticatically triggers the motor which opens the door... but my problem is that how can i activate the motor in forward/reverse...
