Introduction: Make Your Own Motorized Camera Slider

About: Awesome Electronics Tutorials, Projects and How To´s

In this project I will show you how I repurposed two old camera tripods in order to create a motorized camera slider. The mechanical system consist mostly of aluminium and stainless steel which makes the slider sturdy and pretty decent looking. The electrical system consists of an Arduino Nano with LCD, rotary encoder, limit switches and stepper motor. Let's get started!

Step 1: Watch the Videos!

Both video parts will give you a good overview on how to create such a camera slider. But the following steps will still contain some extra useful information.

Step 2: Order Your Parts!

Here you can find a parts list with example seller for the mechanical and electrical parts of the project:

thank you, this is a super project

Thanks a lot for the video GreatScott! i followed your instructions and its working!

i want the camera to move way slower than yours. anyone knows what changes should i make to the code in order to enable microstepping? i thought its easiest to place a dip switch to MS1, MS2 & MS3 of the A4988 with no changes to the code but its not working. i'm totally newbie to arduino and to electronics in general! thanks in advance!

This may be my problem and I have to add more to replicate the keys rotary switch. Too tired now. More another day.

Keyes-KY-040-Rotary-Encoder-Module-Schematic.png

I also fixed the INIT error by updating all Liquid Crystal Libraries. The display needs adjusting to show the letters correctly. My LCD at first did not work till I attend the 10K pull-up resistor. Now the rotary encoder does not work. The one in the description is different from the Keys one in the Video that has resistors in it. When I had seen that all was connected to a 12-volt battery but the circuit diagram displays all 5-volt inputs. The Schmidt trigger 74C14N has a Voltage Range of 2 V to 6 V. But no 7805 or dc-dc converter is in the circuit diagram.

All up I spent two days on this and like it as I am confident to get it going.

Good design. DANKE Great Scott. GUT GEMACHT. (Well done)

First, thanks for the Idea and the greate Tutorial.
After a lot of hours my Slider works!

---------------------------------------

#1
My Aliexpress.com Display doesn´t work with you Code.

After i change the serial port to: " LiquidCrystal_I2C lcd(0x3f, 20, 4) " it works!

#2
The Steppermotor only Vibrates.

in RPM Mode the motor only vibrates, in Time-Mode the Screen jump to HomeScreen.

------
if (!(digitalRead(limit1))) {
lcd.clear();
mode = 0;
minutes = 1; // Test, change to 10min,
stepper.disable();

-------

After Homescreen Jump the time was: 10min.

The problem: Limit-Switches!

If you use the Circuit above, you have to change the Lines:

pinMode(limit1, INPUT);
pinMode(limit2, INPUT);

to:

pinMode(limit1, INPUT_PULLUP);

pinMode(limit2, INPUT_PULLUP);

The other option is to wire a 10k resistor from D6-GND / D7-GND

and the switch 5V-D6 / 5V-D7

Hi, my LCD doesn't shows anything, the motor (6 wires) hold torso and can't move. Rotary encoder doesn't seem to do anything.

Hey I had an similiar problem with the Liquid crystal I2C Libary.

The error occured @ the loop section in line:

lcd.write((uint8_t)0);

I solved it by deleting the old libary files - reinstalled the Liquid Crystal I2C Libary of Frank de Brabander (found in "Bibiliotheksverwalter") and tata it worked...

Probably it helps ...

@Great Scott: I really want to thank you for this great work you did! I play now since 4 month with arduino and tryed to programm a code for a slider with your options... For a newbie too much. Your code is great! I am not finished yet, but soon ;)

Cheers from SW-Germany

you are right this library is good because the examples work correct (Hello World!) but for some reason we still have the 'init' error, while with this one

http://www.archiduino.com/liquidcrystal_i2c-h-library-arduino-ide-1-6-x/ we don't get the error but it doesn't display right , so in the first one something has to be changed , Thanks

I've successfully fix the init error by changing the code:

void setup() {

lcd.begin();

lcd.backlight();

lcd.createChar(0, customChar1);

lcd.createChar(1, customChar2);

pinMode(clk, INPUT_PULLUP);

pinMode(dt, INPUT_PULLUP);

pinMode(sw, INPUT_PULLUP);

pinMode(limit1, INPUT_PULLUP);

pinMode(limit2, INPUT_PULLUP);

attachInterrupt (0, isr0, RISING);

I've done as you have written and pops mistake

I see. As I am also just a newbie, I only can guess what is the problem.

Did you install the wire.h right? This is responsible for the wiring of the I2C! If you answer yes, only the LiquidCrystal_I2C.h could be the problem. And I can imagine your path is still the same of the old library because of \Arduino-LiquidCrystal-I2C-library-master

???

Try this if nothing else works:

Hope you can solve your little problem, good luck!

Cheers

crazy... everything works, BUT the motor (Nema17, 1.3 A, 2.4V) vibrates as hell and doesn't move. When I disconnect the wires for the microsteps... S1, S2, S3 the motor turns, but with a lot of interruptions. Only at 40 rpm a fluent rotation is given. I operate the motor with 12 V 1.7A Adapter.

Does anybody know or have a hint how to fix this problem? I am stucked, after hours of trying.

Is it possible to achieve 1200 rpm on the A4988 stepper driver and the stepping motor nema 17 on that software/ program ?

Stepper Motor Speed

===================
By comparison with regular DC motors stepper motors are very slow devices.

Typical speeds might be 1000 to 4000 steps per second and for a 200 step motor that would represent 5 to 20 rps (300 to 1200 rpm).

Generally speaking the motors with low coil resistance and high currents (and low nominal voltages) will be most suitable for higher speeds. A high voltage will also be needed for high speed.


Acceleration
============
If the stepper motor is required to move a heavy load it will normally be necessary to start the movement slowly (as with any motor) and accelerate to the desired speed and, equally, to decelerate when it is necessary to stop.

This is quite different from a DC motor which will accelerate and decelerate automatically.

If you try to start or stop a stepper motor too quickly it will simply skip steps with no damage to motor. However The Arduino has no means to know whether or how many steps have been missed and all of the position control will be lost.

For this reason, in particular, it is essential to choose a motor with sufficient torque for the job and to use acceleration and deceleration when necessary.

Could you make a slider that keeps the camera to a fixed point. A dual axis one. Where you meassure the distance to the object and it turns the camera while sliding towards an object?
