so i have a thesis about smart parkings and i made a project and while making it and testing since im used to arduino uno more i programmed on it and when im finally done with every feature all working flawlassly with the arduino to transfer it to work as good in esp 32 i faced many issues and im no…

i measured the Vin and its outputting about 4.8v so im using it as the power (im powering my esp with usb)

okay. so that is how you are powering your ESP32. How about all your sensors? You can't just tie everything to V_in at 4.8V since the ESP32 i/o pins only tolerate 3.3V. POST A SCHEMATIC, please.

oh that could be the problem ? cause im wiring everything to to v in and using it as my power source just like i used it with the arduino (vin=5V) and schematics i dont have a simulation that i used i was just adding sensors and changing pins trying and fixing i have a paper that i made for the ard…

[image] mrelo: oh that could be the problem ? Most definitely. You need to check the datasheet of your devices to see if they can run at 3.3V or you need to install level shifters between the devices and your ESP i/o pins. It is not a trivial matter mixing 3.3V and 5V devices. You could al…

i have a arduino wifi module do you reckon i should just stick to uno r3 and use wifi chip? if so do you know how to wire it ? i think it has 8 pins

Which wifi module? I'm sure it has been done before if you google it

i have this im not sure of its name nor even sure it works with my arduino uno if you have any idea artical or video that could help that would be awesome [image]

where did you purchase it? Just a picture isn't helpful.

[image] mrelo: im not sure of its name It looks like a ESP-01 [image]

You could also switch to the new Uno R4 with Wifi The Arduino Uno WiFi Rev 2 is also a board with wifi and 5 volt i/o. It uses the ATmega 4809 processor so there may be issues with all the libraries you use being ported to that processor. You can try test compiling for a proposed target with ou…
