I have a stepper motor with the following specs:
- 5V
- 7.5DEG/step
- 6.5 Ohm
I drive it using a ULN2803A with pulse from a 68HC11 Microcontroller. However, the motor seemed doesnt have enough torque for my application (a little bit more will be pretty good).
So may i know, what are other ways that i can try other than changing the motor? (I've tried increasing the delay, which result in lower speed, but it doenst help).
