<h3 >1. Overview</h3>A simple chess clock to use while playing chess with your friends.The following basic features are implemented:<ul ><li >adjust initial time </li></ul><ul ><li >store last configuration</li></ul><ul ><li >play/pause/reset</li></ul><ul ><li >notify players when the time is over</li></ul><div class="se-component se-video-container __se__float-none" contenteditable="false" style="width: 100%;"><figure style="width: 100%; height: 56.25%; padding-bottom: 56.25%; margin: 0px;"><iframe frameborder="0" allowfullscreen="" src="https://www.youtube.com/embed/pvR09ZHskv4" data-proportion="true" data-percentage="100%,56.25%" data-size="100%,56.25%" data-align="none" style="width: 100%; height: 100%;" data-index="0" data-file-size="0" data-origin="100%,56.25%"></iframe></figure></div><h3 >2. Setting up the environment</h3>Libraries used: <ul ><li ><a href="https://github.com/mathertel/OneButton">OneButton</a> (improving button functionality)</li></ul><ul ><li ><a href="https://github.com/gauravmm/HT1632-for-Arduino">HT1632-for-arduino</a> (interfacing arduino with Sure Electronics led dot matrix)</li></ul><ul ><li ><a href="https://github.com/AlexIII/EEvar">EEvar</a> (storing variables in EEPROM memory)</li></ul>In order to install the libraries you need to download each repo, decompress and place it in the libraries directory in your sketchbook folder.You can find a detailed guide about how to use libraries <a href="https://www.arduino.cc/en/guide/libraries">here</a>.<h3 >3. Wiring the circuit</h3>The wiring of the circuit is described in the attached schematic.For the Dot Led Matrix<ul ><li >Pin 11 to GND</li></ul><ul ><li >Pin 12 to VCC</li></ul><ul ><li >Pin 3 (CS1) to Arduino Digital pin 9</li></ul><ul ><li >Pin 5 (WR) to Arduino Digital pin 10</li></ul><ul ><li >Pin 7 (DATA) to Arduino Digital pin 11 </li></ul>For the buttons and the buzzer<ul ><li >Button 0 to Arduino Digital pin 3</li></ul><ul ><li >Button 1 to Arduino Digital pin 4</li></ul><ul ><li >Button PP to Arduino Digital pin 5</li></ul><ul ><li >Buzzer to Arduino Digital pin 7</li></ul><h3 >4. Running the code</h3>Clone <a href="https://github.com/sstefoss/chess-clock-arduino">this repo</a> and open the source code in your arduino code editor. After importing the code run Verify and then Upload.<h3 >5. Troubleshooting</h3>Cannot include librariesinarduinoeditor?Please read the <a href="https://www.arduino.cc/en/guide/libraries">official guide</a> on how to use libraries and always include them from your editor (Sketch -> Include Library).Buttons/Buzzer not working?Again, you have to make sure that the pins are <a href="https://github.com/sstefoss/chess-clock-arduino/blob/master/main.ino#L10">setup correctly </a>(Button_0, Button_1, Button_PP, Buzzer)Led Dot Matrix not working?<ul ><li >is USER_OPTIONS in HT1632 library set?</li></ul>In the README file of HT1632 library, in the <a href="https://github.com/gauravmm/HT1632-for-Arduino#code">code </a>section you may have missed this: <blockquote >Before running the code, go to HT1632.h and check the <code >USER OPTIONS</code> section and follow the instructions to specify the type of board you are using.</blockquote> <ul ><li > is the matrix connected properly?</li></ul>Please make sure that the PINs defined in the <a href="https://github.com/sstefoss/chess-clock-arduino/blob/master/main.ino#L15">source code</a> (CS1, WR, DATA) match the connections on your arduino or your led matrix.<h3 >6. Future</h3><ul ><li >Implement time increment variation. </li></ul>
