Motorised Camera Slider

In this video I’ll be showing you how I motorised my camera slider. I’m using the existing mounting points to attach the components to the slider, this modification just bolts on using the existing bolt holes.

For this project you’ll need the following:

  • Arduino Nano compatible board
  • A stepper motor
  • Suitable stepper motor driver board
  • 1 Limit switch
  • 2 push buttons,
  • 2 270 ohm resistors
  • Strip board
  • Female header pins
  • Hookup wire.
  • Project enclosure
  • 3mm MDF
  • 4 bearings
  • 8 bolts
  • 4 spacers
  • Stepper motor gear
  • Belt

After I prototyped the circuit on a breadboard I then started to build the circuit on the strip board. I started by soldering some female header pins into the strip board, this will allow for me to insert the Arduino micro compatible board. I then soldered three resistors into the board, these will be used to create a voltage divider for the three buttons used. With the resistors installed I then soldered the the two push buttons and limit switch into the strip board using the hookup wire. Six connections were then made between the motor driver board and the strip board to complete the wiring.

I then connected the setup to a 12 volt power supply to test the electronics before I install it into an enclosure.
We can now install the hardware and stepper motor onto the camera slider carriage. This consists of two laser cut plates, some bearings, spacers and bolts.
