Arduino code for the Camera Slider.


Recently i have gotten some request for sharing the Arduino code for my homemade camera slider.

To start with i just want to say, I’m no master in this, so there can be bugs, and the code is still early and not complete.
Recently i haven’t had much time for these kind of projects, so it has been still for a while.

    Hello again from Greece. Found a solution to make the code work. replaced the swtft part of the code with another tft code. required some work to make it work but ok. if anyone is interested i will upload the code. will come back with photos or video of the working project. thank you Paw Pedersen for the idea.

    Hello Paw, I’ve got every thing working except the display on the tft screen the touchscreen is working but i don’t get any graphics shown. can you please give a hand? I’m not really familiar with coding u see. https://www.elecrow.com/wiki/index.php?title=2.8%27%27_TFT_Touch_Shield#Pins_usage_on_Arduino is the tft screen used but i’m not able to get it working with your code. How can i check what pins to use for the graphics and so on. if you could give me a push in the right direction.
