I bought for this project:
5 Xbee's S2C,
4 Xbee nanoshield
4 Arduinos Nano
1 Arduino MEga 2560
1 Xbee shield for 2560
1 W5500 Ethernet Shield
I will have a page hosted in Arduino 2560.
This page will have 4 buttons, this buttons pressed will send data to arduino nanos via Xbee 802.15.4 network.
Its a simple project to control led 13 in arduino nano.
The Arduinos nanos will have to turn on led 13 and tell arduino mega the led 13 is on/off to switch button color green/red
Can anyone help me start or give me good advices?
