Just wanted to mention, most of car makers since around '96 no longer display the actual coolant temperature. Instead, the arrow stays exactly in the middle in the range of about 75-115 degrees. This is probably because dealerships were flooded with unnecessary questions about the temperature fluctuations (raises in the traffic jam, goes down on the highway), and this solution definitely refuced their headache. I know several "happy" car owners proudly telling the cooling system in their car is so well-designed and working properly that the gauge shows exactly 90 degrees no matter what 😅

All these mods you do combined would make a sick tricked out Sim Racing Rig.👍👍

My friend, instead of a separate image for each position of the indicator needle, it would be much better for your storage unit if you left the background fixed and used a code that would mathematically rotate the pixels of the indicator needle :)

Love your work.
if you ever decide to make a video about using off the shelf automotive sensors like a VDO Pressure sensor and "normal" automotive temp sensors that would be awesome.
the real issue here is getting 12v sensors to work with the 5v arduino...

[robertsavello]

This is great! Been wanting a nice clean and affordable way to monitor intake temps at various points throughout my intake system. This is awesome. Thanks!

[kevinhaylett]

Thank you for your help in these gauge videos - you could simplify your design in terms of images by having the arrow inside the markers and drawn and refreshed with a primitive shape like a long triangle that can be positioned and have a primitive filled round as background (from the tft-library) both can be refreshed and just have a large text for the numbers. You then only need a single image for the outer markers.

i hope my future car someday isn't 34 celsius

Eres bueno en la creación de videos, y la temática es de mi gusto. Te pido por favor que hagas los videos también en el idioma hablado en español, he visto que otros Youtubers sí que tienen esta opción .

[vremennyi]

After your videos I'm thinking about adding digital temperature/pressure gauge to my espresso machine :) There is Gagguino project, current version uses nextion display, but LVGL interface in development. I think there is a great option to add round screen also :)

[Jrok]

That would be pretty rad if you could out put some PWM control for cooling fans with curves.

[DmitriyKhazansky]

This looks great. It would be nice to see examples of how to implement alarming thresholds where the screen would blink or some other way to get the drivers attention.
Also, is this just a proof of concept or would you recommend using this hardware in a car? Are the displays bright enough? Will they survive a car’s harsh environment (heat, cold, sun, vibration, etc)?

[techquirks]

Top-notch content as always!
Do you recon it is possible to write a code that way so the image goes a bit dull at night time. e.g. a positive/negative input from the car to esp32 board that tells it to decrease brignness of the display when headlights are on? just a suggestion

[bimokayoba]

Great idea,
I want to see a tutorial from you of how to use MicroSD card with Ardiuno or Esp32,
and Thank you ♥.

[anotherbloke]

Nice work. I'm looking to rebuild the dashboard in my kit car!

[techconcept]

Another great video with a detailed walkthrough, thanks

I'm also looking to add temp and pressure gauges to my car. I have a Superlite SLC with Megasquirt MS3 engine management. I was monitoring temps and pressures using Shadow Dash on my phone connected via BT. But android updates have made it where it doesn't work anymore. Your videos are priceless. I really appreciate the time, care, and how thorough you are.

My request is to take 6 of these gauges and put them on a single larger display. I saw your Focus RS video, something like that but 2 rows. If it's the same process but just alter the resolution, what display would you recommend? 7" is the largest I have room for.

[Sodwmistis]

great job my friend for one more time, thanks for your videos. i want to ask you if you try to increase memory with hardware for more images. i try to use your ford focus gauge(oil press and oil temp so we talk for about 220 image) but need too many of memory.

[cecemoto]

thanks for this new item each time explanations are quite clear. Now after the temperature and the boost it remains the engine rpm counter- 😁😁 is it planned?

[tubeDude]

Amazing piece of coding! Nice work! 👍

[MathewMaher]

Is there a way to set a warning limit if the temperature gets too hot? I’m sure it’s simple to do with the bitmap images, but what about with the code? For example, if it reaches 200F, set a warning message on the display to “stop, turn off engine, overheating” type message.

This would be an awesome modification for a 1998-2010 Volkswagen New Beetle that didn’t come with any coolant temperature sensor for the driver.
