Go to Wifi Chip

Hey yall, I got a project ive been working on and I would like to incorporate a Wifi aspect to it.

My goal for this project is to take some information from a PIR Sensor and then send that information over to another board so it can be outputted elsewhere.

Do yall have any good Wifi Chips that can send information back and forth to one another?

Which Arduino board are you using ?

Currently using an Uno R3

Wemos D1 mini:

(Not as an add-on WiFi board, this replaces the Uno)

So I can hook up my PIR Sensor here and then communicate with my Arduino through the built-in Wifi, great!

Thank you so much

Do they have a version with pins so I do not have to sauter?

communicate with Arduino through Wifi ? - no, there is no Wifi on arduino
You can use this module to communicate with other WiFi devices

Thats what I meant sorry!

I am just going to get 2 of those so I can send that data to a display that's hooked to one of them

Some do.

But I guess if @bilzzarrd had one of those already, they wouldn't have asked the question.

I assume you meant to write "solder" (or if you are American, "sodder").

I've not seen any with pins already soldered, but then I've never looked for them. They often come with both male and female header pins, and female headers with extra long pins (kind-of like both male and female!), so you can choose and solder whichever you need or want.

Thank you so much!

Yall have been really helpful and I've already ordered 2 of these boards.
I hope it works with everything in my project!

Be aware that the ESP8266 is a 3.3V device. You can not directly connect one of its inputs to the output of the PIR sensor if that PIR sensor is powered by 5V; you will need a voltage divider or level shifter.

What display?

Some displays need a lot of pins, and D1 mini does not have many. So if it's a 16x2 LCD display, best get an i2c backpack for it.

I plan to get a i2c backpack.

But it would work if the PIR sensor is connected to a 3.3V source?

That I don't know; it will be trial-and-error. I personally would try it by connecting the PIR sensor to the 3.3V pin of your Uno in the current setup and see if it works.

What is the problem with 2 additional resistors for a voltage divider.
