Hi,
i need to set two relay shield on a wemos d1 mini.
first is insered like a shield and it work.
The second connect with wemos with this port:
wemos -> relay shield
5v -> 5v
gnd -> gnd
D8 -> D5
D5 is default pin of shield
but second relay not work,
i'm not eletrical expert,
this is data sheet, can you help me please?
Please link to the shield. The schematic is interesting, but lacks context. Please clearly identify all your modules and parts for us.
How are you connecting the second relay module, with jumper wires?
Another thing, how do you know it doesn't work? Did you write a test sketch? If so, please post it. You have been on the forum for a while, so I won't ask for code tags.
In the schematic, I see what look like jumper blocks. You should be able to use two relays on a D1 motherboard (backplane), by setting the jumpers on each one to use a different I/O port on the D1.
