How can I be sure that my device isn't grilled ?

Hi everyone !

I am using two nRF24l01 devices for a school project and I have recreated a lot of cable schematics and ctrl+c/ctrl+v lots of C lines that I found on internet.
I made sure that my wirings are correct but nothing works so I was wondering, maybe at the beginning of my project, I may have connected wrongly the Vcc to the +5V pin of the Arduino instead of the 3.3V pin, and so my composants could have grilled.

So how can I be sure of the condition of my devices ?

Thanks for your help !
(sorry for my poor english !)

Sadly you can't ever be certain. Try them and see if they work. Unfortunately, it is possible to damage a component and have it still work for a while then fail, or work but not quite as it should. A component in this state can be hard to spot. If it fails completely then you know.

I agree with Perry, its very frustrating trying to troubleshoot a device when you can't tell if it is working unless you get both send and receive working.

I would suggest looking for some simple Arduino test code. Reduce your wiring to the minimum needed to operate. Its the best way I've found.

Here on the Arduino forum, we regularly "fry" components, modules and Arduinos, rather than "grill" them.

For particularly spectacular accidents, you can use the term "vaporized", or even "atomized", but your meaning was clear.
