ESP32 and ADS1115 ADC- Voltmeter project

I am using ESP32 , TFT display (240x240) and  external 16 bit ADC module (ADS1115) to measure voltage.I  I just want to show you my simple voltmeter sketch. I am comparing my project with a real multimeter and results are quite good. I haven done any calibration and no external components are used.

Parts used in project:
ADS1115 Module: 
TFT Display 240x240 :

Very nice project and I like how you display the values. Very elegant.

Thank you for another great little project. I am making a solar power monitor and always learn a lot from your code.

Your graphics make my iPhone look like a ZX81 :)

❤sir this is amesing. I am looking for this video. You are the person explain this module in practically. Thank you

Gorgeous Fluke Voltmeter, as always an awesome projekt

I'm always impressed by our graphics design using these tiny screens :) Is there already a video where you go into details what your workflow is coming to this results and use them in your code?

super nice esp32 project 🤩 I would like to monitor a sensor 0 to 10vdc and display the result on a cell-phone using remoteXY Bluetooth.
I wish there was a esp32 module with better analog conversion and isolated would be even better all on one board. 🤔 thanks a lot for the great info. 😎

🆒 Excellent video! Thanks from whole 🇵🇰

Thank you very much sir, the video was very helpful. It is very well explained, best regards.

I guess the ADS1115 have differential inputs. That's also nice to have.

Thanks bro this is amazing video thanks ❤️

Are the SDA and SCL pins at different voltage levels between the ADS1115 and the ESP32? I don't know if those pins on the ADS1115 are considered output, input, or both. I was thinking both. So I thought the pins on the ESP32 are not supposed to exceed 3.3 V?. Although I have accidentally hooked up 5 V signals to the ESP 32 pins and it seemed to be OK.

Great video
Thank you.
Question: can the i2c read data from the ads1115 when it is connected to 5v.
I was under the impression that you would need a level shifter.
Kind regards

Great Vid! What is that gray wire running from the ADC to the TFT?

PS Nerver use a blue bridge cable for a Positive Jumperline as you showed in 6min12. LOL Why? out of cables? No Front -just funny. Please keep on creating.

@Volos Projcts "Hello, thank you very much for sharing your projects! They help me learn alot about basic electronic programming (I am a beginner). My question is, could I measure based on diodes with this project, by modifying it? Could you perhaps make a variation?

Hello, what software were used to make the pictures used in your project? Can you provide a tutorial? For example, the picture of fluke

[markuspfaff]

great Video an your other projects :-) have a simple question: if I need no +/- range, but a range from 0V to 2, 5V with the best resolution of the ADS1115. I dont know, I have to programm this effect. 0V to 2, 5V shout be a digital value 0 to 65536. Is that possible?

Excelente proyecto, me encanta la gráfica del display... Eso con un micro STM32 es posible manejarlo, o tiene poca memoria, digamos un 030? Cómo el de la Bluepill. Saludos desde Córdoba Argentina

Hi thank you for this, I have made it but my display flashes at about half second intervals? The picture is solid, just the digits. I have spent two days and cannot find the reason have you any idea to help me please? Anyone? Bob. UK
