Stepper Motor Control - speed control This program drives a unipolar or bipolar stepper motor. The motor is attached to digital pins 8 - 11 of the Arduino. A potentiometer is connected to analog input 0. The motor will rotate in a clockwise direction. The higher the potentiometer value, the faster the motor speed. Now, upload the below program in your Arduino UNO and open the serial monitor. As discussed earlier you have to rotate the potentiometer to control the rotation of the Stepper motor. Rotating it in clockwise will turn the stepper motor in clockwise direction and vice versa. Hope you understood the project and enjoyed building it. Intro: BLDC Motor Control With Arduino, Salvaged HD Motor, and Hall Sensors. There is a lot of interest these days among hobbyists in controlling brushless DC (BLDC. ROB-09238: This is a simple, but very powerful stepper motor with a 4-wire cable attached. This program was designed to control the speed of a stepper motor. The speed was limited to between 0 RPM and 60 RPM. No cable box required. Cancel anytime. Find out why Close. PES-2605 is an easy-to-use stepper motor controller for Arduino Uno and Mega, which uses micro-stepping method to precisely control stepper motor. Library and example for the stepper motor controller are part of of PhpocExpansion library for Arduino.
Most people who are involved with DIY 3D printers or just like tinkering with a Maker-Grade commercial printer, will have heard of the Trinamic series of stepper motor driver chips. These little chips are making waves throughout the consumer and prosumer 3D printer markets due to their astonishing ability to render a 3D printer practically silent.

The TMC2208 is also used by the German manufacturer Watterott in their SilentStepStick stepper motor driver product series. However, there is very little information written in layman's/Maker's terms regarding how to actually wire up this stepper motor driver board, to a traditional Ramps 1.4 to 1.6 style Arduino shield, in order to use the feature of serial communications over UART to control the stepper motors. In this Instructable, I will try to alleviate this by taking you through a step-by-step setup of how to use a TMC2208 based SilentStepStick in a UART configuration on your 3D printer.

EDIT-August 2018: When I originally wrote this Instructable, the default Pin assignments within Marlin were different from what they are now. The photo above shows my Y-cables in different positions to what they would be now, in the current version of Marlin. See Step 10 for details on how to find these current Pin assignments.
