Abstract
A programmable digital chess clock is provided that includes a QR code reader (or other 2D and/or 1D barcode reader) for reading a QR code or barcode that encodes instructions for programming and setting the digital chess clock. The digital chess clock includes a microcontroller operatively arranged to program and set the digital chess clock, wherein the QR code reader or other barcode reader is operatively arranged to read the QR code or barcode and send a signal to the microcontroller to program and set the digital chess clock.
Claims18
A programmable digital chess clock assembly, comprising:
- a) a programmable digital chess clock comprising a microcontroller operatively arranged to program and set the digital chess clock without transmitting radiofrequency data to or receiving radiofrequency data from an external device;
- and
- b) a QR code, other 2D barcode, and/or 1D barcode reader operatively arranged to read a QR code, other 2D barcode, and/or 1D barcode encoding instructions for programming and setting the digital chess clock and send a signal to the microcontroller to program and set the digital chess clock;
- wherein the microcontroller is further operatively arranged to program and set the digital chess clock based only on the instructions from the QR code, other 2D barcode, and/or 1D barcode reader and not from tapping and/or holding one or more buttons on the digital chess clock.

A programmable digital chess clock, comprising:
- a) a housing;
- b) a display mounted in the housing and operatively arranged to display time associated with a first player's clock and operatively arranged to display time associated with a second player's clock;
- c) a first switch mounted in the housing and operatively arranged to stop the first player's clock and start the second player's clock when activated;
- d) a second switch mounted in the housing and operatively arranged to stop the second player's clock and start the first player's clock when activated;
- e) a microcontroller operatively arranged to set and control the first and second players' clocks without transmitting radiofrequency data to or receiving radiofrequency data from an external device;
- and
- f) a QR code, other 2D barcode, and/or 1D barcode reader in communication with the microcontroller, and operatively arranged to read a QR code, other 2D barcode, and/or 1D barcode encoding instructions for programming and setting the digital chess clock and send a signal to the microcontroller, wherein the signal is used to set the time on the first and second players' clocks;
- wherein the microcontroller is further operatively arranged to program and set the digital chess clock based only on the instructions from the QR code, other 2D barcode, and/or 1D barcode reader and not from tapping and/or holding one or more buttons on the digital chess clock.
