thunder Posted June 20, 2006 Report Share Posted June 20, 2006 Hello alli sent asking about how to make my counter works properlywellnow the matter became so horriblei'll tell u what i did & need anyone to tell me comment & guide me coz this is my first practical work, im working lonely too, no teamplz dont laugh at mei got an optocoupler & biased it , im sure of it's connection & it gives output pulses when the motor disc rotates btween it's both sides (photo diode & receiving transistorthe motor disc is simply a piece of strong paper that i made in form of circle & made it's edge like a gear ( i made 16 holes on the circumference)output pulses from opto coupler i use it as the clock , input to my counterthe counter 74193 , i connected it as follows:it's four input pins-----to groundpin 16---vccpin8--- groundload pin---vcc through 1kohmclear pin-- to groundi connected the four output pins to leds inorder to check the countwell,, im supposed to connect the carry pin to a second counter 74193 as a clock, so that each 16 pulse (each motor cycle) the second counter will count 1,,, & then i'll connect it to a decoder 7447 & seven segmentnow i connected the whole circuit except the second counteri thought of checking what i did first, b4 i continuei connected the 1st counter directly to the decoder 7447but hoplessly it didnt count at allwhen i wasnt connecting the decoder, it was counting but stupidly1 5 7 1 5 7i connected a capacitor as the degnified sir told me, but still stupid countit's awful in both casesi dont know what to do!!!!!!!!!!plz help meeeeeeeeeeeeeeeeeeeeeeim so sorry for making it long on uwaiting ur repliesbyeMODERATOR EDIT: I have moved this post to it's own topic for more exposure.
