Two 10k pull up resistor s are at the SDA and SCL pins. This is due to the reason that DS1307 communicates through I2C interface. SDA – Arduino pin A4; SCL – Arduino pin A5; Next, wire up the LCD ...

Clock jitter is generally regarded as any deviation from the expected clock behavior. In real life, it is a cycle-to-cycle variation. Suppose you have a 100 MHz clock, with a period of 10 ns.

Maker Michael Klements has built a unique electromechanical clock using a little Arduino hardware, code, and 28 servos, which tilt panels to reveal the correct time in digital format.

I used V-USB for a couple of projects with my own code from scratch (i.e. No Arduino etc) and they work fine. I am using Win7 X64+libusb and use Vendor Specific commands only.

The Arduino Nano microcontroller is central to the operation of this pendulum clock. It processes the data from the accelerometer and controls the timing of the electromagnetic coil’s push.

Options to power the Arduino Nano include USB, VIN, and 5 volt pin, ... I/O pins (14 pins), and the same processor clock ... such as monitoring serial data received or produced by the Arduino.

Just when you thought you’ve seen every strange variation of clock there is to see, we find one based on an Arduino that tracks the phases of the moon. The “Lunar Phase Clock” is a project ...

You have a timer and clock in just about every single device out there these days, but if you want to build you own, Instructables user GeraldF6 shows you how to do so with a Arduino.

The idea here is to use a cheap clock from IKEA, wire in a bunch of LEDs, connect and Arduino, and then use the 1Sheeld to trigger color changes depending on the traffic time between two points.

Real time clock . The new board also features an RTC (real time clock). Ranellucci said, “We added three new pins. There is a pin which allows users to turn off the board, saving power except for the ...
