Hi,
I have 2x arduino nano and a cheap 433 MHZ TX and RX modules attached to them.
I have tested the Transmission and reception and they work fine.
My problem is that when I add a TM1637 8 segment module the reception stops working.
The Transmission is working fine and the arduino with the TX modules shows succesfull
transmission LED blink.
The arduino with the RX module stops receiving signal, however if I remove the jumpers
that connect the 7 segement module then the arduino starts recievign the signal again
with no problems.
I tried changing the pin order for the CLK and DIO of the TM1637 module and it doesnt make
any difference, I also tried changing the 3v input to 5v and still not working.
The TM1637 module itself has no problems and I have checked by making it display random
numbers and they all show fine. The display also works when attached to the arduino that
has the RX module but then the reciever won't pickup any signal.
what seems to be the issue here? is it hardware related or software related? I use Virtualwire
library for RF modules and TM1637-master library for the display.
