Fix LED's on eBay 28BYJ 48 Stepper controller motor <br /> <br />An LED on the controller board for a 28BYJ 48 Stepper was not lighting. So I carried out a test and found the soldering to be poor quality on the board. After re soldering the board the LED's worked fine. <br /> <br />To help test the boards I wrote a sketch for the Arduino to sequence the LED's so I could see if they where working or not. <br /> <br />NOTE: <br /> <br />Not to test a stepper motor but just to see in the board seemed to function as expected without a stepper motor. <br /> <br />This will Not make a stepper move it is only to turn the LED's on and off in turn to see if they are working. <br /> <br />Arduino Leonardo Compatible Code:- <br /> <br />File : <br /> <br />test_LEDs_stepper_controller.ino <br /> <br />http://1drv.ms/1x47kyB <br /> <br />.
