For information on how to setup uStepper in the Arduino IDE, visit our GitHub repository at
www.github.com/uStepper or have a look at our videos on YouTube - search for uStepper.
More information/documentation on the uStepper Arduino library is also found in the readme
section on out GitHub repository.
Q: I can’t program uStepper from the Arduino IDE, what is wrong?
A: Three most common issues:
 If you use the Windows store app “Arduino IDE” you might experience problems. Down-
load the executable or portable version of Arduino IDE from www.arduino.cc
 Install hardware support and the uStepper S-lite library
 Remember to chose uStepper S-lite as the board you program to
Q: When I run uStepper closed loop PID or Drop-in the motor spins up and runs fast in one di-
rection, what is wrong?
A: Two most common issues:
 Check that the encoder magnet is placed correctly on the motor shaft
 Check that your PID parameters in the Arduino code are sane. A good starting point is to set
P and I to 0.5 and D to 0.
