Flowing pictures show the stepper motor and connection bridge circuit board: Step 1 - Connect Arduino, Bridge board and Stepper Motor as per following graph: Step 2 - Download stepper. The motor turns clockwise just fine, but it doesnt turn anticlockwise. It can control two motors running at 4. …In other application, you might need to use the two axises…to control the movement of two motors and so on. Now in Anti-clockwise button's function, paste the below code at the of the function to rotate the motor in anti-clockwise direction. Is it okay if my stepper motor has exactly 4 wires? Wires are colored: white, blue, red, yellow. If you want to make the projects, like thermoelectric generator,arduino stuff, a digital microscope,solar phone charger, robot,hand crank generator etc. Here I wanted to concentrate on the theory behind using Arduino or another MCU to drive a three-phase Brushless DC electric motor such as a CD or DVD drive (or HDD for that matter) spindle motor, such as the one pictured further in the text. The stepper is controlled by with digital pins 8, 9, 10, and 11 for either unipolar or bipolar motors.
