Or you can use Pin Change Interrupt on Atmega328p which is in every pin of Atmega328p (Arduino Uno, Nano, Pro Mini)

Great video! Have tried to work this code for simultaneous motor control, but the motor is not moving smoothly as in the video for the speed and acceleration, its like its starting and stopping each step till final position causing a juddering sound and slow motion of the motors... i cant figure out why its not running smooth

How about s-bus or ppm? Very few people have an I-bus Tx/Rx combo lying around

Two years later and this tutorial is still one of the best. Short, concise and incredibly helpful. <3

Nice video... This can be used to create an data aquisition with a sampling rate of 1000Hz (ADXL3750)?

Can you explain more about direction and pulse pin? I used uln2003 and 28byj48 stepper motor with pin connected to 8, 9, 10, 11 hole. For programing i'm still a very beginner level and i used to find other video write a pin as #define pin1 = 8, pin2 =9, etc. So can you please help me give some suggestion for the coding or the schematics of my arduino?

Great video... Can I use 10k potentiometer ?

Will I need 2 arduinos for 2 stepper motors, how should I be able to connect 2 stepper motors to the throttle with only 1 arduino?

Thanks for releasing a well thought out video about this, got it sorted quickly.

Is this possible but over wifi with a nano 33 iot?.

Thanks for the video . Could you please share the link to your blog ? Thank you

Thank you so much!!! Plan to build a vertical lift bridge (Custom Model Railroads) this winter for my HO railroad layout. Thought about using two dual-shaft steppers, one for each side of the bridge, with two thin steel wires for each side of bridge. With some experience with Arduino & steppers, I have been thinking about how to synchronize the two steppers even though I'll still employ limiting micro switches for top and bottom travel on each side of the bridge. You solved the issues for me with the Accelstepper library and your clear examples!!!

HELLO SIR CAN YOU PROVID ME CODE

wait where is your website? where can I find the wiring diagram?

you can leave an example using the L298N

C:\Program Files\Arduino IDE esources\app\lib\backend esources\arduino-serial-plotter-webapp\static\js useState)(50) welcome

where did you get the code from

Thanks a lot for this video, I was not having much luck in robotics yesterday and this just saved my day!

Very informative....Thank you..

Thank you Can this same code be used when using two tb6600

// From ua-cam.com/video/UZKxUFkwCc8/v-deo.html #define RCPin 2 volatile long StartTime = 0; volatile long CurrentTime = 0; volatile long Pulses = 0; int PulseWidth = 0; void setup() { Serial.begin(9600); pinMode(RCPin,INPUT_PULLUP); attachInterrupt(digitalPinToInterrupt(RCPin),PulseTimer,CHANGE); } void loop() { if (Pulses < 2000) { PulseWidth = Pulses; } Serial.println(PulseWidth); } void PulseTimer() { CurrentTime = micros(); if (CurrentTime > StartTime) { Pulses = CurrentTime - StartTime; StartTime = CurrentTime; } }

Hi, is it possible to connect Arduino with most popular fs-gt5 receiver? I just want make electric rc car with using stepper motors. But one important thing, I need to use fs-gt5 controller

Thank you very much❤ Tell me please, can I use it with nema 8?

Great video and very helpful! One question, what is the reason that the Arduino R4 version doesn't work?

Could i get PCB;)?

You have a really great way of explaining things and go into enough detail for someone like me that has very little knowledge of these things. I wish you had more content. Keep up the great work. Thanks for sharing.

Amazing, Thanks man.

Hi, can you please add the detail and specs about material used in description of video. Like Motor (voltage/current) rating, battery (voltage/current) rating, Type of Arduino used etc. Thanks.

Does the baud rate need to be that high or can it be 9600?

This is what I needed to know, thanks a lot. I'm building a solar tracking system but didn't know how to get info about the photoresistors. If you had any code for solar tracking using photoresistors and a linear actuator I'd really appreciate it.

can i stop the motor at specific angles ?

This is cool!!! Thank you.

Banger of a tutorial !

Thank you so much for the content 🙏🏻 I want to ask, can the program be used if using a 3 phase AC motor and using a relay as the contactor? Thank you in advance🙏🏻

As others have said your code explanation is excellent! I am thinking of implementing this to control three ball valves - I just need to know do stepper motors have free movement when unpowered? I ask this as I need to consider how I can provide manual override in the event of power failure or other faults. In your opinion would stepper motors be suitable for my use case? Thanks

Is there a way for us to find The script for your arduino program, so we can copy and paste? The library I downloaded only shows "blocking", unlike in the video's "blocking_fixed_position"

So, if I want to run DC motor follow a sinewave. What I have to do?

Thx bro

very helpfull!!!

Great video, well explained! Using PID, can you achieve absolute position control with these encoded motors? Thanks!

I am just getting my feet wet with this, and this video is incredibly helpful!

thanks so much its realy useful

The code for those who want to try it out : import serial import matplotlib.pyplot as plt from matplotlib.animation import FuncAnimation import csv # Constants SERIAL_PORT = 'COM4' BAUD_RATE = 115200 # Initialize serial connection ser = serial.Serial(SERIAL_PORT, BAUD_RATE) # Initialize empty list to store data x_vals = [] sensorValue_data = [] # Create a function to raed and process data from Arduino def read_and_process_data(): line = ser.readline().decode('utf-8').strip() sensorValues = line.split(',') x_vals.append(float(sensorValues[0])) sensorValue_data.append(int(sensorValues[1])) # Print the received values print(f'Time: {sensorValues[0]}, Sensor 1: {sensorValues[1]}') # Creat a function to update the plot def update_plot(frame): read_and_process_data() plt.cla() plt.plot(x_vals, sensorValue_data, label='Sensor') plt.xlabel('Time') plt.ylabel('Sensor value') plt.legend() # Creat a function to save data to a CSV file when the plot window is closed def on_close(event): with open('arduino_data.csv', 'w', newline='') as csvfile: writer = csv.writer(csvfile) writer.writerow(['Time', 'Sensor']) for x, s1 in zip(x_vals, sensorValue_data): writer.writerow([x, s1]) # Register the callback function for when the plot window is closed fig, ax = plt.subplots() fig.canvas.mpl_connect('close_event', on_close) ani = FuncAnimation(fig, update_plot, interval=10) plt.show()

Thank you so so so much !! This is exactly what I needed, short and effective, really good tutorial.

thanks

Is anything like this able to be done with an elrs rc link?

Thanks bro Does anyone know what is the x axis, like is it milliseconds or is it related to the baud rate

Thank you!

Thank you! Phenomenal video! I love the style I love the explanations, to the point and easy to follow!! You may was to consider adding to the end of the ser.close() in the in_close() function. My system doesn't automatically close serial communication and this may save some headaches for other viewers as well!

since arduino is running before the python script activates the time stamps do not start at 0. is there a way to make the timestamp start at zero once the python code starts?
