Use DIP Switch To Set Arduino Device Net ID And Node ID for Wireless Communication
To use one remote control to many switch radio frequency wireless power supply sockets, each one must has its unique ID to identify itself and act according commands received from the remote control.
In the example sketch,A2-A4 A1-A3 are set to 1, 0, 1; D2-D9 are set to 0,0,0,0,1,0,1,0. So the net ID is calculated as 1*4+0*2+1*1=5; node ID is calculated as 0*128+0*64+0*32+0*16+1*8+0*4+1*2+0*1=10.
Updated on Nov. 12, 2014
Use the same DIP setting above, the output will be :
Net ID: 5
Node ID1: 0
Node ID2:10
