1 The PC GadgetMaster II Stepper Motor Control Developed by Frank Shapleigh Edited by Jim Tuff

2 Simple Variable “Contains” numbers, characters or strings of characters. Contents of a variable change each time an assignment is made. Eg. X = 1 X = 2 X = 3 X = 4 X 4 Stepper Control Variables Explained

3 Array Variable Array “Elements” can also store numbers, characters or strings of characters. Elements and their contents are referenced by an “index”. Eg. A(1) = 128 A(2) = 64 A(3) = 32 A(4) = 16 One Dimensional array A( ) Stepper Control Array Variables Explained 1128 264 332 416

4 Example: Private Sub Command1_Click() A(1) = 128 A(2) = 64 A(3) = 32 A(4) = 16 S = 1 Text1 = A(S) End Sub Stepper Control Array Variables / Digital Output Text1 Displays the value of A(1) S = (1) = 128 Digital Output 1 (128) is 12 volts

5 Example: Private Sub Command1_Click() A(1) = 128 A(2) = 64 A(3) = 32 A(4) = 16 S = 3 Text1 = A(S) End Sub Stepper Control Array Variables / Digital Output Text1 Displays the value of A(3) S = (3) = 32 Digital Output 3 (32) is 12 volts
