Evocation of this clock signal applies Astable Multivibrator circuit by using IC 555 as core circuit. this functioning Clock arranges rotation frequency of motor stepper. Output frequency excelsior from IC 555, rotation excelsior of motor stepper. So do on the contrary. Under this is drawing schematic diagrams from signal generating clock:
As which has been shown to picture is upper, output characteristic from this circuit is square wave continue with frequency and duty certain cycle. Level of frequency influenced by value R1, R2 and C3. If it is required to change value, we can change it is using component variable which certain is level causing can be changed at any times as according to our desire. While switches is upper applied to joint and drops the ball to the next circuit.
This attached if in a moment we to wish to stop motor stepper, so that enough opening connection rotation clock so desists. Signal clock which in the form of square wave continue functioned for input signal counter. this Circuit applies D Flip-flop as IC core in circuit. From motor input characteristic data stepper, obtained eight different conditions. To create it is required [by] 8 level of calculation signal, and after reaching storey to 8 will return to duck's egg. Eight different conditions obtained from representation with 3 data bit having combination of bit counted 8.
This is diagrams schematic of counter clock signal:
