Using Step Motor
Step motors allow controled rotation. They implement it using steps. To use it - you need controller.
My controller for step motor 28BYJ-48 has 4 input channels. To make one step - we must send 8 singals in sequence:
Step | IN1 | IN2 | IN3 | IN4 |
---|---|---|---|---|
1 | 1 | 0 | 0 | 0 |
2 | 1 | 1 | 0 | 0 |
3 | 0 | 1 | 0 | 0 |
4 | 0 | 1 | 1 | 0 |
5 | 0 | 0 | 1 | 0 |
6 | 0 | 0 | 1 | 1 |
7 | 0 | 0 | 0 | 1 |
8 | 1 | 0 | 0 | 1 |
