jean28 0 Posted March 15, 2014 Share Posted March 15, 2014 Good day guys, I bought this stepper motor to play around: http://www.amazon.com/gp/product/B00DUSYEWY/ref=oh_details_o02_s00_i00?ie=UTF8&psc=1#productDetails It includes the very useful ULN2003 test board, which I am using to interface the MSP430 with the motor. The MSP430 is working perfectly fine (the Pins that are turned on have 3.3V), but the motor doesn't turn around. I am thinking that the reason that it isn't working is because I am powering the test module with the 5V that my Raspberry Pi provides. I think these motors need around 500mA to work. Is there a way for me to get those mA to make the motor work? I have left a picture of what I am trying to do so you guys can see. Thank you! Quote Link to post Share on other sites
