This module comes with a power indicator LED at the back. Note: There is an 8-way right angle header pin, so you need to break it into a 4-way pin and soldering is needed. It has an integrated serial input/output common-cathode display drivers, which enables a microcontroller such as Arduino to control 4 digit 7-segment with just two output pins. This is TM1637 based serial 4 digit 7-segment LED Display Module.
#ARDUINO 4 DIGIT DISPLAY SERIAL LIBRARY CODE#
Remove the following lines of code if you want a static instead of a blinking center colon:ĭisplay.showNumberDec(displaytime, true) // Prints displaytime without center colon. Display the current time in 24 hour format with leading zeros enabled and a center colon:ĭisplay.showNumberDecEx(displaytime, 0b11100000, true) Print displaytime to the Serial Monitor Int displaytime = (now.hour() * 100) + now.minute() This line sets the RTC with an explicit date & time, for example to set The following line sets the RTC to the date & time this sketch was compiled: Serial.println("RTC lost power, lets set the time!") Check if the RTC lost power and if so, set the time:
Begin serial communication at a baud rate of 9600 TM1637Display display = TM1637Display(CLK, DIO) Define the connections pins for TM1637 4 digit 7 segment display This library allows an Arduino to easily display numbers and characters on a 4 digit 7-segment display without a separate 7-segment display controller. * Degital 24 hour time format clock by Arduino, TM1637 4 digit 7 segment display and DS32321 RTC.*/ For more information, you can check out the DS3231 datasheet below: / DigitalReadSerial Reads a digital input on pin 2, prints the result to the serial monitor This example code is in the public domain. The DS3231 IC is made by Maxim Integrated. Restart the Arduino IDE, open one demo code you like, for example ClockDisplay directly. Unzip and put them in the libraries file of Arduino IDE by the path.
