Virtuabotixrtc.h Arduino Library ((better)) -

The DS1302 uses a 3-wire serial interface, which consists of a Reset/Chip Enable pin (RST/CE), a Serial Data pin (DAT/IO), and a Serial Clock pin (CLK/SCLK).

First, create a global virtuabotixRTC object. The constructor takes the three pins you used for the CLK , DAT , and RST connections, in that order. The DS1302 uses a 3-wire serial interface, which

// Set the current date and time (seconds, minutes, hours, day, date, month, year) myRTC.setDS1302Time( loop() { myRTC.updateTime(); Serial.print( "Current Time: " ); Serial.println(myRTC.hours); delay( Use code with caution. Copied to clipboard Considerations and Alternatives Legacy Status The constructor takes the three pins you used

To use the library in your Arduino sketch, follow these steps: Open the Arduino IDE.
