This was an excellent video. I’ve been looking for a way to design a pixelated image just for this reason and got a bonus virtual test for the arduino and screen out of it. I’m very much a visual learner so this changes things for me. To be able to make small changes to the code and then simulate the results without any physical changes to the hardware will save time and make retaining the information much more efficient for me.

If I would use the middle of the bar as the zero point (so 2,5V from the potentiometer) and would like to fill the bar to the right when voltage goes above 2,5V and fill it to the left when voltage is below 2,5V how would I do it? Use if analogRead < 511 ug8.drawbox (and numbers to get it from the left side to the center) and map it to 511,0,62,0 to get it inverted and if analogRead>511 u8g.drawbox (from the center to the right side) and map it 511,1023,62,124? No idea, just guessing as I can't test it right now 😁

@upir_upir Год назад

Yes, that´s one of the ways how to do it. I have done someting similar for one of the version of this project where also the zero was not all the way one the left side. For simplicity of the tutorial (it was already quite long), I have decided to not go into negative values for now. Good luck with your project!

@upir_upir 2 года назад

Hello and thank you for your comment. I’m currently experimenting with a real sensor, and it has three wires-5v, ground and signal. Based on the pressure, the signal goes from 0-5v, so it’s actually very similar to using potentiometer. You just need to correctly assign the values.

How to understand the connection of the display with arduino? why are two analogue inputs are connected to display why not one? what is their significance.

@upir_upir Год назад

There is no analog input connected to the display. All the pins to between Arduino and Display are digital. Search for the "Arduino Pinout" to find out which pins are used for SPI or IIC communications. You can use other pins as well, but in that case, the SPI and IIC will be done via software and thus much slower. Hope that makes sense!

For 2nd page Y=8..15 and so on. After complete of drawing one page, framebuffer is sent to appropriate "page" of LCD RAM, number of page is incremented (Y range also) and for this new conditions library needs another drawings - loop until u8g.nextpage Don't know if it helps and is clear, sorry for my rusty english 🙁

Hello! Would you sell one of these to me? with turbo boost and egt readings?

@upir_upir Год назад

Thank you, but I´m not selling those. You are free to use the design and components and do it on your own, perhap even better :) What is egt?

@BaZZmuZ Год назад

Will it work as well with an LCD display?

@upir_upir Год назад

It should be possible, but you would want to use a different library, not u8g. Actually, the easiest path would be to use intelligent display, for example Nextion of DWIN. See some examples here - ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-NpZMQjdKxBI.html ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-t21-wF5F41Y.html

If i use an smaller OLED display but with the same resolution 128x64 i will have to modify the photo? Also, i live in Europe and we use BAR as a measurement if i change the numbers in the .psd will it work?

@upir_upir Год назад

Yes, you can use any display size, as long s as the resolution is the same, you don’t need to change any code. I have a lot of 128x64 OLED displays varying from very small to quite big and they all work as expected. Changing the numbers in photoshop file will surely work, but you can also directly render text to screen. Please see my other videos for more details.

@@upir_upir if you don't mind one last question. I've got an electronic boost sensor and how can i find out if it works well with the potentiometer that u used?

@upir_upir Год назад

The boost sensor should be used instead of the potentiometer. In many cases, the boost sensor will act like a potentiometer (voltage divider), you just need to assign the correct value to a particular voltage.

@comandor7713 Год назад

Great project, but upir, slow down a little bit, because for a beginner, it's a real ordeal... too fast. Maybe an experienced arduino architect is able to master it, but a common novice dies in this after 5 minutes

@upir_upir Год назад

Thank you for your comment, I will keep that in mind, but hopefully beginners could use the playback speed options to slow it down. I usually watch all the other youtube videos at higher speed...

@winandd8649 Год назад

Ok, a turbo boost gauge without a pressure sensor.. or do have have to turn the knob myself while accellerating? 😂

@upir_upir Год назад

Well, that’s one way how to do it, but probably not very convenient one. You can get a pressure sensor that reports the pressure using different voltage, and replace the potentiometer. I plan to record another video how to do that.

Are you making a Arduino toy or a pressure indicator

This particular project is a pressure indicator, but I have some newer videos with Arduino games - please feel free to watch them.

Where is CAN Bus chip and codes?

@upir_upir 2 года назад

The idea is to connect it directly to the sensor, but you can surely try CANBUS. I don´t have such tutorial yet, but I plan to record it in the future.

@user-lz1vh5pc5c 2 года назад

@@upir_upir CANBUS communication will be quite slow, compared to tapping in existing sensors. I'm currently running similar setup im my car. I read the sensor every 100ms, cause i think it's unreadable if the analog read is flickering like crazy. Also for precise measurements i use external 5v reference, which is filtered.
