![]() The library has a function built-in that makes setting individual segments a bit easier. Create array that turns all segments on:Ĭonst uint8_t data = TM1637Display display = TM1637Display(CLK, DIO) Create display object of type TM1637Display: ![]() * Example code for TM1637 4 digit 7 segment display with Arduino. You can copy the code by clicking the button in the top right corner of the code field. Use this image as a reference when setting the individual segments in the code later. The segments are labeled A to G and some displays also have a dot (the 8th LED). Two pins are required for the power connections and the other two pins are used to control the segments.ħ-segment displays contain 7 (or 8) individually addressable LEDs. Thanks to the TM1637 IC mounted on the back of the display module, this number can be reduced to just four. That’s quite a lot and doesn’t leave much room for other sensors or modules. is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to products on .īare 4-digit 7-segment displays usually require 12 connection pins.
