In this tutorial, I will show you how to create simple analog clock with Arduino UNO and OLED display with 128x128px resolution, using the u8g2 library and WOKWI online emulator. The display uses SH1107 chip, but we will be using the SSD1306 128x64 OLED display for testing inside the WOKWI.

I don't know if I've ever seen anything so well explained! Greetings and thanks!

@upir_upir Год назад

Thank you for your nice comment, I´m glad it was helpful and good luck with your projects!

@Chilternflyer 5 месяцев назад

I'm a visual learner and only have limited c++ experience. This is a very clear and detailed explaination without drifting off the task. I find this easy to follow and also learning about the libraries at the same time :-) Subbed!

@upir_upir 5 месяцев назад

Thank you for your nice words, I’m glad it was helpful! Please feel free to also check my other videos and good luck with your projects.

@rayansattarkhan6807 Год назад

Wow! I learned lots of new things from this video. Really great. Please keep creating.

@upir_upir Год назад

Happy to hear that! I´m glad it was helpful, and I will surely try to record more...

@kickbaktube Год назад

I think I understand how to use Modulus in code now. Thank you.😀

@jorgeestefania3184 Год назад

It can also be used to set the seconds back to 0 every time it hits 60. If you set the seconds to seconds % 60, if the seconds are 60 it will be set to 0, so you can save yourself an if statement. 19:00

@upir_upir Год назад

I’m glad it was helpful! As for the other comment, yes, you can do that for seconds, but you would still need the if statement to increment minutes and hours..

@NicleT Год назад

That was a real class. Bravo!

@upir_upir Год назад

That´s great to hear, thank you for your nice comment!

@gerhardachrainer6116 Год назад

Since it‘s just black and white, I‘d draw the hands in black using previous time (to erase it), then in white again. That would avoid drawing the background each time.

@upir_upir Год назад

Yes, that should be possible, but sometimes the hands are displayed over tickmarks, so you would have to also keep track of that and “repair” any damaged tickmarks. I mean all of this is possible, but it would probably not affect performance that much.

@gerhardachrainer6116 Год назад

@@upir_upir So now you got me curious: what direction would you think of when optimizing performance in this specific scenario?

@upir_upir Год назад

@@gerhardachrainer6116 The u8g2 library supports partial redraw/update of the screen, so I would start there. Also switch the IIC display for a SPI version, that would speed things up as well. And if nothing works, switch to UNO R4, any other faster Arduino clone or ESP32.

@wibbley1 26 дней назад

Yep, draw the second hand in black, before redrawing it in white in the new position. Then redraw in white the minute & hour hand to repair any damage. (if using different colour for second hand, redraw it again, as it should be above other hands) Only need to draw minute & hour hand in black, then new position in white, once per minute. Make the hands shorter than the clock markings, so they do not need to be re-drawn. You will find the clock hands look much smoother.

@upir_upir Год назад

soo... have you used this 128x128 display for any project?

@Shamanestr Год назад

i don`t. 128X64 is way cheaper. For that money you can buy 1 pcs "128x64" + "1.8" LCD Display TFT Screen Module SPI Interface 128*160"

@yupingliao4078 3 месяца назад

Without the RTC (1307/3231) module installed, will the Arduino ino’s time in seconds be accurate? Will the time remain the same when you turn off the power and turn it back on again?

@upir_upir 3 месяца назад

It will most likely not be accurate. If you don´t want to use an external RTC, you can use microcotroller that has already RTC build-in, for example Arduino UNO R4.

@masterdeki Год назад

Do some video for drawing on 3.5 inch displays, lets say some car gauges :-)

@upir_upir Год назад

Which exact display do you have in mind?

@petermoore9504 Год назад

I made a digital clock using a similar 1.5 inch display (maybe the same one) and the burn-in was terrible. After only a few months it became unusable, maybe take the brightness down? Cheers.

@upir_upir Год назад

That’s interesting. I will keep it running and see how it looks in a few months. I have other oled displays on for weeks and I don’t see any burnout pixels yet.

@phakalanep7241 Год назад

A very good project - But please slow down your explanation you are very fast it's hard to see what you are trying to explain

@hiperformance71 Год назад

😂, he is very fast, you can slow down the video too, he need to cover a lot in those tutorials.

@upir_upir Год назад

Thank you for your comment. Could you perhaps use the playback speed to slow it down?

@iamkian Год назад

Hello. Thank you for sharing. Can you please do a howto for a "Waveshare 2.9 inch E-Ink E-Paper Display - 3 Colors" using a Nano or Uno? Thank you.

@upir_upir Год назад

You are welcome. I can take a look. Is there any particular project that you would like to use this display for?

Nice, why don't you use images for dial and needles?

@upir_upir Год назад

You can. There are multiple ways how to achieve the same result..

@roostertechchan Год назад

17:24 wouldn't it be easier if you just draw a rectangle instead of two triangles? You know the 4 points already.

@upir_upir Год назад

It would, but there is no function to draw rotated rectangle in the library.

@roostertechchan Год назад

@@upir_upir ah, I didn't know that

@EasyOne Год назад

nice

@upir_upir Год назад

@Wokwi Год назад

Great again! What if Wokwi had 128x128 SH1107 ?

@upir_upir Год назад

Well, that would be really great and it would also mean that for many of my future projects would be my preferred display 🙂 however, it would be enough to have support for any 128x128 display supported by u8g2 library, because at that point, switching the initialization should be simple.

@Wokwi Год назад

@@upir_upir Thanks for the feedback! It's possible to add new displays (like the SH1107) using the Custom Chips API. Are you interested in trying it? There's a complete example of an IL9163 SPI display implementation in the Chips API documentation.

@upir_upir Год назад

@@Wokwi That all sounds great, but I´m worried that I don´t have enough knowledge yet for something like that. Has anyone created any custom display for WOKWI already?

@Wokwi Год назад

@@upir_upir Yes, there are three examples so far: SSD1306, ILI9163, WS29V2 (2.9" epaper) display. RU-vid won't allow links here, but you can find the first two in the documentation site under "Chips Api" -> "Getting Started". There's a "Chip Examples" section with "Displays" category.

@upir_upir Год назад

Thank you for your reply, I did take a look and the documentation is really great, especially with all the custom chips already made. That said, unfortunately right now, it’s beyond my knowledge. But maybe someone else would be about to add that bigger display, that would be great.

Yes, the u8g2 library should support this display.

try rotary radar display, it will be awesome
