LinkNode Module : 4Dig-7Seg uses a chipset of TM1637 to drive a 12-pin 4-digit command anode 7-segment LED. The MCU only needs two GPIO lines to control it.
Wiring
The module is connected to the base shield J1:
Module CLK --> LinkNode D1 G0
Module DIO --> LinkNode D1 G1
Install Library
* download library :
Place the TM1637 library folder your ”arduinosketchfolder/libraries/ folder”.
