1/29/2024 0 Comments Led alarm radio clock![]() The DS3231 real time clock communicates with the Arduino through the I2C communication, so we have included the wire library. The wire library is for the I2C communication between the DS3231 and the Arduino. VCC on the DS3231 to the 5V pin on the Arduinoįinally, connect the positive of the buzzer to pin 11 on the Arduino and the negative the of buzzer to GND on the Arduino.Īrduino Alarm Clock Code #include #include #include LiquidCrystal lcd(2, 3, 4, 5, 6, 7) DS3231 rtc(SDA, SCL) Time t #define buz 11 int Hor int Min int Sec void setup() Code Explanation First of all, we included the libraries for the DS3231 real time clock and the LCD. Start your morning with local news by using this GPX alarm clock radio.GND on the DS3231 to GND on the Arduino.Then connect the DS3231 real time clock module to the Arduino as follows: ![]() This is the negative pin of the backlight. This is the positive pin of the backlight. Pin 15 to the 5V pin on the Arduino through the 220- ohm resistor.Connect the data pins (D4-D7) to the pins 4, 5, 6, 7 on the Arduino. ![]() LED auxiliary lights LED inspection lights Headlight restoration kit Health and Wellness. Learn why these radio & alarm clock suit your needs.
