Wokwi Simulations for Arduino Built-In Examples

[DaveX]

Other Libraries might be interesting. Here are some stepper motor control library example simulations:

Stepper.h

• https://www.arduino.cc/reference/en/libraries/stepper/
• GitHub - arduino-libraries/Stepper: Stepper Library for Arduino

Examples

• MotorKnob Simulation -- Stepper position follows a potentiometer reading
• stepper_oneRevolution Simulation -- Stepper bounces back and forth 200 steps.
• stepper_oneStepAtATime Simulation -- Stepper moves slowly at 2 steps/sec
• stepper_speedControl simulation -- Stepper speed varies with potentiometer reading

MobaTools MobaStepper

• GitHub - MicroBahner/MobaTools: Arduino library for model railroaders

This library moves steppers with acceleration in the background, and supplies a lot of other functionality (Servos, Buttons, LEDs, timers)

Simulations

• Example 2 -- bounce a stepper back and forth between extremes with acceleration and a Finite State Machine
• Example 3 -- Stepper jog buttons and speed control
• Stepper Button Example -- Move stepper to five different absolute positions based 5 different buttons.
• Stepper Reference Example: Set a reference position with a limit switch and move to specific positions with button presses.
• Stepper Reference_2 Example: Three axis steppers with X,Y homing cycle
• Stepper Slider: Use buttons to set end locations and initiate a travel.
• Other Examples: MobaTools/examples/_Stepper at master · MicroBahner/MobaTools · GitHub

AccelStepper

• AccelStepper Documentation
• Github code mirror
• AccelStepper The Missing Manual and Examples

This non-blocking library uses a smooth acceleration scheme to move steppers.

Examples

• AFMotor_ConstantSpeed
• AFMotor_MultiStepper
• Blocking
• Bounce -- Simulation: Bounces +/-500 steps
  • Simulation with STEP/DIR driver
• ConstantSpeed -- Simulation: one stepper at 50steps/sec, 15RPM
• DualMotorShield -- Simulation: two steppers bounce back and forth at different speeds.
• MotorShield
• MultiStepper -- Simulation: two steppers in coordinated motion to multiple positions (no acceleration)
• MultipleSteppers -- Simulation: Three steppers with acceleration
• Overshoot -- Simulation: Demonstrate overshooting past 300 and smoothly returning to 0.
• ProportionalControl -- Simulation: Follow potentiometer position with acceleration.
• Quickstop -- Simulation: Accelerate towards +/- 500 but stop ASAP after +300&0 subject to acceleration limits. (With an improved simulation)
• Random -- Simulation: accelerate to random positions with random speeds and accelerations.

FastAccelStepper

• FastAccelStepper Documentation & other docs
• FastAccelStepper Repository

Examples

• StepperDemo -- Simulation

Servo

• Documentation: https://www.arduino.cc/reference/en/libraries/servo/
