![]() In this tutorial we will learn everything we need to know about controlling stepper motors with Arduino. So int duty 0.5 is going to get rounded to either 0 1. Stepper Motors and Arduino The Ultimate Guide. What's the difference what are they trying to say it's not clear to me. You need to review your code and also the capabilities of the Arduino UNO. I don't understand the first two blocks where it says "the following are used if the DC/stepper noted is in use" and "the following are used if any DC/stepper are used". The following pins are used only if that particular servo is in use: ![]() The following pins are in use if any DC/steppers are usedĭigital pin 4, 7, 8 and 12 are used to drive the DC/Stepper motors via the 74HC595 serial-to-parallel latch The following pins are in use only if the DC/Stepper noted is in use:ĭigital pin 11: DC Motor #1 / Stepper #1 (activation/speed control)ĭigital pin 3: DC Motor #2 / Stepper #1 (activation/speed control)ĭigital pin 5: DC Motor #3 / Stepper #2 (activation/speed control)ĭigital pin 6: DC Motor #4 / Stepper #2 (activation/speed control) Well you cant because the arduino analogWrite() function uses chip hardware timers and the timers are hardwired internally in the chip to just specific pins. They can also be used as digital pins (pins #14 thru 19) Here's what they say on their FAQ page:Īll 6 analog input pins are available. ![]() I just use their library and tell the motor to take 10 steps forward or 10 steps backward. The Arduinos programming language makes PWM easy to use simply call analogWrite(pin,dut圜ycle), where dut圜ycle is a value from 0 to 255, and pin is one of the PWM pins (3, 5, 6, 9, 10, or 11). What if I connect something to pin #10 and the motor shield was using it? What would happen?Īnd I am using the motor shield library and just initializing an object of their library class so I don't know what's going on under the hood. Yes the shield has headers and it reveals the pins of the uno R3 but I don't know if those pins are being used or not.
