Motor Control

Demonstration
Instruction
1. Button functions include manual Control, change of stepper motor speed, input angle to move stepper motor. Button A goes down the menu. Button B goes the opposite. Press both A & B buttons enter the selection.
​
​
2. Press both buttons simultaneously to start, which will bring up the main menu with 3 options:
Option 1: Pressing button A moves the stepper motor counterclockwise, which stops when the south pole of the
magnet reaches the hall sensor. Button B moves the motor in the oppsosite (clockwise) direction and stops due to
the north pole of the magnet instead. The LCD displays certain variables like its direction and steps taken. Pressing
A & B returns to the main menu.
The hall sensor can produce a range of values. When pointed at with a magnet's north pole, the value goes below
450 and when pointed with the south, it increases past 510. These values are used to determine when the motor
stops in Option 1 and may be different for another hall sensor.
Option 2: Button A increase the stepper motor delay by 100 microseconds. Button B is used to reset the delay to 0.
A & B are pressed to return to main menu.
Option 3: Requires the user to input an angle (0 to 360), with A or B buttons to increase & decrease the angle
value. (200 steps gives 1 full rotation.) A & B are pressed to enter the selection, turns to the desired angle. It then
returns to the main menu.
