Storing Data from an Arduino wirelessly (WiFi/Bluetooth)

Projects Interfacing w/ Software on the Computer

Hello!

I'm tasking myself with making a autonomous (ex) remote control car that follows a series of magnets along the floor. Most of it I am fine with, but I would like a way to save the readings from the magnetic sensors so that I can analyse it later on. For saving data off something such as an arduino wirelessly, would it be best to attach via a tiny computer (Rasp Pi) and store it there, or transfer the data by Wifi to my computer directly?

I couldn't find another feed like this but apologies of it is a repeat. I would really appreciate some advice in any form and I can repay you with copious amount of happy emojis.

Have a great day!

No. The Arduino can use the WiFi shield (somewhat reliably) to make GET requests to a server as easily as the Pi can.

Storing the data on an SD card is far more reliable and cheaper.

I agree with @PaulS's recommendation to save the data to an SD Card connected to the Arduino.

If you do want to have a WiFi connection then I suggest you consider a Yun.
