Stepper Motor Forward And Reverse Testing circuit.
Using NE555,CD4017 and ULN2003 to build a stepper motor testing circuit with forward and reverse.
NE555 - astable circuit with adjustable frequency.
CD4017 - Decade Counter/Divider with 10 Decoded Outputs, using it to strobe the ULN2003, adding 8 1N4148 to control the stepper motor to forward and reverse.
ULN2003 - seven darlington transistor arrays, using it to drive the stepper motor.
