Quartz Clock Arduino

If you want to build a clock that has decent accuracy, your best bet is to use a 32768 Hz quartz crystal, as suggested by Ignacio Vazquez-Abrams in his comment. I did that on a bare ATmega chip a quotbarebones Arduinoquot to make a 24-hour analog wall clock. You should be able to easily adapt the code I published in that page to fit your project.

Arduino Analogue Clock Controller. Remotely Drive, AdvanceRetard amp Adjust Pulse Timings Of Up To 6 Quartz Clocks . Functions. Controls a single clock but includes an option to control up to 6 clocks. Clock info displayed on a 1.8quot SPI TFT display. TFT display shows RTC time, temperature daily minmax temperature, humidity, last sync time.

The Arduino quotkicksquot the quartz crystal with a 5V pulse Due to piezoelectrics, this results in the crystal vibrating at its resonant frequency 10 MHz and releasing a pulse back into the circuit This pulse travels to the first IC inverter and splits, one section going through the 560 Ohm resistor and one through the IC

I'm trying to control a quartz clock mechanism with an arduino. I've watched video after video and all I seem to be doing is destroying mechanism after mechanism - except I have no idea if I'm breaking them, they just don't work and this process seems to be one way. 16541206 368 KB.

This instructable shows how to build an Arduino Quartz Clock Controller and is based around FLORICA TUDOR-NICUSOR's Clock With Alarm, Hygrometer amp Thermometer.. This controller will remotely drive, advanceretard amp adjust pulse timings of upto 6 Quartz Clocks and is ideal for controlling clocks than are difficult to reach.

The Arduino decodes the DCF77 time signal from Germany using Udo Klein's DCF77 library v3 but using the appropriate library and some modification to the code should be able to use any world wide radio time code. The Arduino Code is based on my Master Clock code and has been completely re-written for Udo Klein's V3 library by Peter Hillyer.

The Arduino site states that the arduino uno has a 16MHz Quartz Crystal, but I'm measuring a frequency accuracy of about 0.35 which would be typical for a ceramic resonator instead of what i could expect from a quartz 0.001. It is purely used to clock the ATMega16U2 chip which provides USB connectivity USB requires a higher accuracy

You can do this from a microcontroller like an Arduino or Arduino-compatible derivative, or from an embedded Linux processor like a Raspberry Pi or BeagleBone, as long as you have digital IO pins GPIO to connect to the solenoid's pins. Most quartz clocks run on one or two AA batteries, meaning that the solenoid runs on either 1.5V or 3V at
