Hello,
I use this shields:
https://www.arduino.cc/en/Main/ArduinoWiFiShield https://www.adafruit.com/product/1141
when i connect the three shields, (arduino uno + wifi shield + datalogger shield) the wifi shield is not recognized, but if i remove datalogger shield it works... I don't understand SPI protocol, i think i need that. Can someone explain to me how i solve my probleme?
Thank you so much!
