Motorized Camera Slider Part 3: Circuits and Code

[@smellyoulater]

Love your Slider project so much, I built it! This was my third Arduino project ever. I modified the build and code to suit the parts I had on hand. Still very much a beginner at programming. Loving the motion in my Timlapse videos! Thank you for putting in all the hard work and posting this video series for all to share.

[@berlib0102]

Amazing videos about a superb project! I'm going to make it following your very clear explanations. Many thanks!

[@michaelradil15]

Thank you for sharing this build with us. I am currently testing the electronics and i’m finding that the chip on the Easy Driver gets really hot when the motor is standing by. I have the current at the lowest setting. The motor turns properly and resets but then the driver overheats. I have already burned out one driver. Was this a problem for you?

Great Work - A really good video showing how to build the Camera Slider. I am planning on motorising a Neewer carbon fibre camera slider using the code you have shared as a base starting config. (I am new to Arduino coding). I intend to add a Move, Shoot, Move option which triggers the cameras shutter via another output pin when the slider stops between moves. I noticed in your videos you actually use several different models of Arduino, but provide the code based on a MEGA. I intend using an UNO or NANO, would it be possible for you to share the specific "Interval Pin" details and anything else specific needed for these other two models ? ManyThanks.

[@wogified1139]

Thanks! Its been a while since I made this video tutorial series so my memory of it is a little hazy. I believe I went with the MEGA over the nano/uno due to dynamic memory constraints. This was mainly due to using the OLED display library (its a memory hog). If you choose to omit the screen in order to go with another control scheme, then you can potentially use the nano or the uno. You stated "interval" pins but I'm assuming you meant "interrupt" pins? Those pins are different between the mega and the nano, while the nano and uno may share the same interrupt pin numbers. I recall including some references in the code to websites that really helped me on this topic. If not, it should be a short googling away. Good Luck.

Really great project Wogified! Thanks for sharing!! Very nice coding as well!

[@andrewnorth2976]

will you be adding a camera trigger function to this project, saves messing about with camera settings to fire the shot Nice project btw

[@wogified1139]

Nah, I wasn't planning on it. I dont own any camera with an electronic trigger input. It would need to be something that would physically press the camera button. Possible, but not really worth the effort in my opinion. This rig is meant to be more of a "set and forget" type deal.

[@updomekk]

realy Great work. Thank a lot for your shared.

[@jaysonnicolas2664]

Hi. Just subscribe to you and thanks for sharing this. Anyway upon verifiying the code it display " a8 not declared in void setup". I just starting in my arduino codings so my knowledge is limited. Again thank you.

[@RicardoSequeira]

Hello, my slider is more portable (40cm), to adjust the time do to the 40cm lenght i need to adjust the chassislengh of the code? now is 22500, this nmber corresponds to witch lenght of slider? thank and keep the good job!

[@wogified1139]

Yes, you'll need to tweak that number to your custom length

[@ゆパパ]

is this number in millimetre? ex, 40cm should put 400?

[@Persianppc]

did you find out about the units of this number ? tnx btw :)@@ゆパパ

[@ゆパパ]

@@Persianppc No, but you can put a number to try, and will find one fit yours. My slider is 80cm, the number I think is around 16500

[@Persianppc]

thanks pal ;)@@ゆパパ

[@BikerNic]

Hi there. I'm just starting out with arduino and camera sliders. I bought an Arduino Uno, GBRL shield and High current DRV8825 stepper driver for this purpose. Do you think this will work?

[@wogified1139]

you would be able to achieve the same level of functionality but you won't have enough of the arduino's dynamic memory left for the display.

[@RicardoSequeira]

Hello, i already buy all the items and connect everything but the menu does not fit in the screen, can you tell me what is wrong or if I need to change anything. Thanks

Hello ,I had the display problem also but I had found what the matter is. You can found the Folder path:Arduino>libraries>Adafruit_SSD1306-master>Adafruit_SSD1306.h.Found this program and edit it like this: -----------------------------------------------------------------------*/ #define SSD1306_128_64 // #define SSD1306_128_32 // #define SSD1306_96_16 /*=========================================================================*/ and then ,Compile and upload. Have fun!

[@berlib0102]

problem... I can only go to Quick Access and when I click, the motor is always "zeroiing"... What is wrong?

[@satb7226]

Check A8 (limit switch)

[@berlib0102]

@@satb7226 Many thanks! But... what should I do exactly ?

[@satb7226]

@@berlib0102Hi Bernard, apologies for the delayed response - did you manage to resolve in the end? FYI - on my build, the trigger pin A8 was wired incorrectly causing a similar issue.

[@berlib0102]

@@satb7226 ​ Many thanks for your answer! Unfortunately, my slider is still "zeroiing"and the screen remains on the first option which can't be selected... I despair of finding the solution for this amazing project which is however the most interesting found on the Internet! Do you appreciate your slider?

[@satb7226]

Hey Bernard L when stuck in "zeroing" is the motor moving?

[@iway3030]

my slider is not as same length as yours. so i waant to reverse diection as soon as it hits the limit switch whatever be the time duration is set , i just want it to reverse direction, otherwide it will damage itself if it reaches the end and doesnt stop or reverse. i dont know any programming and completely dependent on you. till now the program runs well but havent fitted on actual hardware. i have added two limit switches at either end making them parallel connection. also my menu fonts are too small , how to increase its size so as i can read. i triesd increasing font size to 2 at many places, but texts just gets cropped on screen and is useless. please help soon. i have invested lot in parts.

[@wogified1139]

What you want to do is simple enough to achieve, but you should take a look at how a simple circuit is wired up for a switch in the arduino IDE. See how the logic works and then try to incorporate it into the code I have provided. There should be many examples of how to do this on google. As for the font issue, its a little trickier due to how the text is rendered on the screen. If you increase the font size, you will also need to shift the starting point down in order to display properly.

Hi it says ''exit status 1'' Error

[@patricklambrecht3934]

I am not seeing the wiring diagram in the descriptions...

[@wogified1139]

Woops, I added the diagram to the github link. You should be able to get it there.

[@patricklambrecht3934]

First of all, great job with this. Building this is so much cheaper than buying one. Secondly, I followed everything in the instructions, and everything seems to be working just fine, except that my rotary encoder does not seem to want to scroll through the menu. I can long press to select, but cannot scroll to any options other than the first. Thoughts?

[@wogified1139]

Not too sure about this. If the button press works, but the knob doesnt work; then I would double check your wiring. Also, in my build, the menu does not respond until you turn it at least a half turn.

[@patricklambrecht3934]

Perhaps I have the wrong resistors. Are those 220s?

[@berlib0102]

Hey sorry for your troubles, but you'll need to provide more information about your issue if you want help on it!

[@ゆパパ]

you chose the wrong board, should be "arduino mega"

[@MSVSanjok]

Why Mega?
