Introduction
Linker 4-digit 7-segment module 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.
Schematic
Sample Code and Setup
Hardware
We connect according to the following:
- D2 of Arduino to CLK of Linker 4-digit 7-segment module
- D3 of Arduino to DIO of Linker 4-digit 7-segment module
- +3.3V of Arduino to VCC of Linker 4-digit 7-segment module
- GND of Arduino to GND of Linker 4-digit 7-segment module
Software
