i’m relatively new to Arduino and programming in general
i’m currently working on a project using 1 Arduino Uno and 4 Nanos.
The plan is that the 4 Slaves (Nano) gather data from sensors and if demanded by the Master (Uno) they send it via SPI.
I’ve looked at https://www.arduino.cc/en/Reference/SPITransfer but i don’t get smarter by that.
Has anybody done a similar project or knows how i get this done properly?
