I want to drive a unipolar stepper motor using Arduino and Motor Shield:
Here is the motor driver: http://www.ladyada.net/make/mshield/
And this is the stepper motor:
The stepper motor consists of 5 pins, 4 to the driver, and 1 to the positive power supply
Then I supply the driver 5V from Arduino Uno microcontroller.
From another power supply I supply +6.5V to Stepper motor, with all the ground connected.
But it results very hot in the L293D IC in the driver, the motor also didnt work well even the coding has been ok.
Is there a way to solve this?
Do I need to replace the driver?
Any suggested driver so I can control the motor using Arduino code?
Is my connection right?
Thank you very much...
