Find the Arduino code here. | |||
Note: 9V external power supply is necessary for driving a stepper. The USB power supply is not sufficient since it has a current limit. | |||
Do please turn off the power supply, if you want to exchange the connection of the 4 pins of the stepper. Or it may damage your circuit because it may generate an inverse voltage. | |||
Micro step can let the stepper slower and also quieter, but it is less accurate compared with a full step. With the easyDriver, you have options of 1/2, 1/4, 1/8 micro step. By default the easyDriver will drive a stepper with 1/8 micro step. And it can be altered by setting the MS1 and MS2 Pin High and Low. | |||
The [http://www.schmalzhaus.com/EasyDriver/ documentation] of easyDriver can be found and you can find the datasheet here. | |||
