have used the design of this circuit for a project was required for me but i faced a problem after making it . the reading of the display doesnot stay on a fixed numbers it changes rapidily and also doesnot give the actual reading . all the connections is right . HINT: i didnot use the diplay MAN6960 as shown in the explain of the circuit couz i didn't find it in stores but i think that doesn't make a problem couz i used a common anode displays. please i need a solve for this poblem?
