If you can, paste your sketch below and I'll try and help figure out why yours isn't working.

What problems are you having? Is your board on? Did the sketch upload correctly? Is it just the LED won't Blink?

Also, make sure your LED is in the correct direction. Since current will only flow in one direction from anode to cathode, you may just have your LED backwards which would result in it not lighting up.

No problem! Glad it helped!

This was just white PLA 1.75mm

I can try and muddle with the align tools I suppose

Haha much appreciated!

Thank you so much!!

Not necessarily. While a lot of videos show it printing standing up, I've had success printing it laying down

Glad it could help you out!

I would need to see your program before I can offer a suggestion. Would you mind pasting your program?

@@quicktechtutorials7289 it's the same that mantas posted below, but the delay is 20.

@@cezarmihnea It looks to be the digital pins you are using. I just rebuilt the circuit and used pins 3, 5 & 6 and used mantas program and it works fine for me. Try connecting the red pin to pin 3, green to 5, and blue to 6 and make sure to change that at the beginning of your program. I also pasted a program that I tested and works. Let me know if that helps int red=3; int green=5; int blue=6; void setup() { pinMode(red, OUTPUT); pinMode(green, OUTPUT); pinMode(blue, OUTPUT); digitalWrite(red, HIGH); digitalWrite(green, LOW); digitalWrite(blue, LOW); } //define variables int redvalue; int greenvalue; int bluevalue; void loop(){ // put your main code here, to run repeatedly: #define delayTime 20 //fading time between colors for(int i = 0; i<255; i+=1) //fades from red to green { redvalue-=1; greenvalue+=1; analogWrite (red, redvalue); analogWrite(green, greenvalue); delay(delayTime); } redvalue = 0; greenvalue = 255; bluevalue = 0; for(int i = 0; i<255; i+=1) //fades from green to blue { greenvalue-=1; bluevalue+=1; analogWrite (green, greenvalue); analogWrite(blue, bluevalue); delay(delayTime); } redvalue = 0; greenvalue = 0; bluevalue = 255; for(int i = 0; i<255; i+=1) //fades from blue to red { bluevalue-=1; redvalue+=1; analogWrite (blue, bluevalue); analogWrite(red, redvalue); delay(delayTime); } }

@@quicktechtutorials7289 Wow! Thanks a lot. I will try it.

While there is no button that will automatically flush the object to the workplane, if you click on the object, you should see a small black triangle over the object. If you click and drag on that black triangle, you should see a black line with an arrow appear next to the object as well a measurement showing how far off the object is from the workplane. You can click in the box showing the measurement and type in 0 and hit enter and it will snap the object flush to the workplane. Hope this helps!

Thanks for the tip!

You're welcome! Glad it helped you out!

So happy the video helped you out!

Awesome! Glad it helped you out!

@Richard Hosking it's not necessarily the wrong way of printing it. I found by doing it laying down, I didn't see any layer lines when the light showed through. Nothing wrong though with printing it standing up

.1mm layer height. 100% infill. Print speed 50. Initial layer speed 15.

@Richard Hosking awesome, keep me posted! If there's a way I can do this better, I'm all for it

@@quicktechtutorials7289 You lose a lot of detail with the print laid down. All the lines are .4 wide so your .1 setting doesn't really do much.

@@brucewhite4531 not necessarily. the .1 setting will impact the detail based on how thick I make the lithophane. Each additional layer provides less light showing through so if I made the total thickness 2.5 mm vs 4 mm, there is a difference in the detail and how much contract the lithophane has.

Awesome, glad it helped!

Happy I could show you this!

Sure thing! Will try and get a video up within the week!

Happy the video was able to help you out!

if you're trying to have a delay for 2 seconds, it would be written as delay (2000);

Tq

What do you mean by two line? If you provide a little more detail, I will try my best to help you out!

@@quicktechtutorials7289 sorry I mean to put text into two rows

@@riyadh1121 No Worries. While there is no specific option to create multiple rows of text, I would simply duplicate the first text row you created. In the duplicated row, I would change the text to whatever you would like it to say in the second row and then move that duplicated row into the position you want. Finally I would group both of those rows together so they will move and change size as one object. Hope this helps!

One thing I would look at in your design is the thickness of the other sides that aren't showing up once you slice the model. For example, if your printer settings in Cura has the nozzle size of .4mm and thickness of the model is below that, Cura may not actually be able to make that portion of the model because it's too small. Check it out and let me know if that was the issue. Hope this helps!

Sorry I don't have those parts at the moment but I plan on making a video on how to control LED strips with Arduino.

While it doesn't have to be Arduino specifically, you would need some type of microcontroller and board or an IC chip that you can program and build into the LED circuit

Awesome!! Happy the tutorial helped you out!

So happy the video helped you out!

Sounds like you may not have the correct Arduino board selected. In the Arduino program, go to "Tools" at the top and go down to where it says "Board" When your cursor is over that option, a menu should pop up with all different arduino boards. Select the model that you are currently using and try that. Hopefully the fixes the issue!

You're welcome!
