4 Digit Two Wire Display With Arduino

I was working on a project where i needed a 4 digit display but when I went to connect it to the Arduino all I found were articles about having to wire up 12 plus pins. Then I found this Suli library which makes it so simple a dummy like me can wire it up with two pins (digitial 2 and digital 3).

Stuff needed:

Grove TM1637 4 Digit display

Suli library

Four_Digiit_Display_Suli library

If you have an Arduino with an I2C two wire plug then it's a no brainer.

I only had an Uno so connect display vcc to 5v, gnd to gnd, DIO to Arduino digital pin 2, and CLK to Arduio digital pin 3.

Done.

Get Suli library here: https://github.com/Seeed-Studio/Four_Digit_Display_Suli

Now I did have a problem running the demo until I copied the cpp and header files from

here: https://github.com/Seeed-Studio/Suli/tree/master/Suli_Arduino (Guess they had updates).

Get Four_Digit_Display here: https://github.com/Seeed-Studio/Four_Digit_Display_Suli

Hope you know how to install libraries.

Run the Four_Digit_Display demo in the Examples file.

Rock on!
