How To Connect A Stepper Motor With IR Remote Control To Arduino (Lesson 32 of Elegoo Mega 2560 Kit)

[@movies4lifers322]

Hi there! great video, loved that you went in depth about everything. Just a question since I'm new to this whole thing, is it possible to create a sequence of clock wise and then counter CW with one button?

[@BMonsterLaboratory]

Hi there movies4life R&S! Yes, you can create a CW / CCW spin with a push button. Do you want 1 full rotation CW and then 1 Full rotation CCW just once per button push or continuous? Thanks for asking!

hello bmonster i did try this one i see me that the remote give signal to the remove reciver but nothing move the motor what could be the cause ?

[@BMonsterLaboratory]

Hi Olivier! Did you double check your wiring? Are you using external power for the motor? If yes to both of those, can you share the code you're using ?

[@olivierlandry1195]

​@@BMonsterLaboratory yes i did recheck the whole wiring and i use external power . the little power board have the green led on . ill join the code i used #include "Stepper.h" #include "IRremote.h" /*----- Variables, Pins -----*/ #define STEPS 32 // Number of steps per revolution of Internal shaft int Steps2Take; // 2048 = 1 Revolution int receiver = 12; // Signal Pin of IR receiver to Arduino Digital Pin 6 /*-----( Declare objects )-----*/ // Setup of proper sequencing for Motor Driver Pins // In1, In2, In3, In4 in the sequence 1-3-2-4 Stepper small_stepper(STEPS, 8, 10, 9, 11); IRrecv irrecv(receiver); // create instance of 'irrecv' decode_results results; // create instance of 'decode_results' void setup() { irrecv.enableIRIn(); // Start the receiver } void loop() { if (irrecv.decode(&results)) // have we received an IR signal? { switch(results.value) { case 0xFFA857: // VOL+ button pressed small_stepper.setSpeed(500); //Max seems to be 500 Steps2Take = 2048; // Rotate CW small_stepper.step(Steps2Take); delay(2000); break; case 0xFF629D: // VOL- button pressed small_stepper.setSpeed(500); Steps2Take = -2048; // Rotate CCW small_stepper.step(Steps2Take); delay(2000); break; } irrecv.resume(); // receive the next value digitalWrite(8, LOW); digitalWrite(9, LOW); digitalWrite(10, LOW); digitalWrite(11, LOW); }

[@olivierlandry1195]

when i press the remote i see the reciver led but i never see any led into the stepper controler board

[@BMonsterLaboratory]

@@olivierlandry1195 it looks fine so far. Have you tried reducing the delay? Try 500 and 1000 ? That may help.

[@BMonsterLaboratory]

@@olivierlandry1195 I can get the parts and put this together and see how it acts for me. The code looks fine though.

[@BMonsterLaboratory]

I have lots more to learn about stepper motors, for sure! Will definitely have some practical projects using steppers in the future. If you need help setting up the Arduino IDE, check this video out kzbin.info/www/bejne/i5q0aJV7j8mphck - Thanks for watching!

[@ramanjeetsingh8684]

Is there a way to keep the motor rotating until the button is released?

[@BMonsterLaboratory]

Hi Ramanjeet. Great question! My first instinct would be to post what I think would work. I would like to put this together on a breadboard and test it before I post the code, that way there's no confusion. I'll post it in this thread and on the Facebook page for others to see when I get home from work. Thanks for asking~

[@SrgntBlntPasser]

@@BMonsterLaboratory I'm currently working on trying to figure this one out too. Have you discovered anything? I'm having a hard time figuring out how to change the speed. It will either move very slow, or slightly faster where each button press is sending a burst of steps, not ideal.

[@BMonsterLaboratory]

@@SrgntBlntPasser hey there! Try this video out kzbin.info/www/bejne/rpyrY3iAnNGqmM0 After buying a NEMA 17 stepper, I probably won't use the one in this video again. Most stepper motors don't have a fast speed. Higher torque = lower speed. What kind of project are you using a stepper on? Are you using the same sketch as I am in this video?

[@SrgntBlntPasser]

@@BMonsterLaboratory I'm trying to DIY my own telescope autofocuser. I have it currently working with 2 buttons and a potentiometer. I hold a button down and it rotates continuously at a speed defined by the Pot and it stops when the button is released. But the idea is to not touch the scope so I'm replacing the buttons with the remote and then replace the Pot with a High and Low setting on the remote.

[@SrgntBlntPasser]

@@BMonsterLaboratory I am extremely close I needed to add a case for when the button in not pressed, and only step 1 time per loop, and set a delay time for each loop. Now I just need to find the max and min delay needed to set my high and low. I'll post a video on my other channel and get back to you when I do!

[@BMonsterLaboratory]

Hey there Jamie! Thanks for the comment. I appreciate it. Just curious, do you have the correct board, processor, and port selected in the tools menu of IDE? Have you tried uploading with another USB on your computer and using that port? Give that a try and let me know.

[@jamiethompson1082]

Sorry, today is my first day coding and using this gear. I realized that I had not set it to UNO in this case. There are no errors now, but the unit does not work. Not sure if you have any private lessons?! OR if you would simply look at my setup. THX

[@BMonsterLaboratory]

I was looking at your code. replace the first line of your loop with this "if (irrecv.decode(&results)) // have we received an IR signal?" you just left out the results of your decode. let me know how that works.

Hi there! you need to download the IRremote library. You can do it through Arduino IDE under library manager or get it from github. It needs to be downloaded before you include it in your program. Hope that helps! 👊👍

Hi Abid! I'm sorry, I just haven't had a chance to try this out. It looks like you're using an IR remote control. Have you double checked the IR button codes? Can you get the code to work at all or do you just get an error message? Great to hear from you
