TM1637 Red Digital Tube LED Display Module & Clock for Arduino LED TM1637Display display(CLK, DIO) //set up the 4-Digit Display.ĭtBrightness(0x0a) //set the diplay to maximum brightnessįor(numCounter = 0 numCounter < 1000 numCounter++) //Iterate numCounterĭisplay.showNumberDec(numCounter) //Display the numCounter value There is a library for this IC, you can get it from , as usual there is a built in example but here is a simple sketchĬonst int CLK = A13 //Set the CLK pin connection to the displayĬonst int DIO = A12 //Set the DIO pin connection to the display Here is how to hook the module up, the good news is this worked with my LOLIN32 and 3.3v Schematic esp32 and tm1637 display Can be used for Arduino devices, two signal lines can make the MCU control 4 8 digital tube.Four common anode tube display module is driven by IC TM1637.Display common anode for the four red LED.This is a common anode 4-digit tube display module which uses the TM1637 driver chip Only 2 connections are required to control the 4-digit 8-segment displays A common display module that you can buy on the internet contain the Tm1638 driver chip, I was interested in this one which is the TM1637 which appears to be a more basic version which can only control a display, the TM1638 can also control LED’s, buttons and two displays at the same time. ![]()
