h files used to store different data constants making up custom characters and melodies, all of which is included in the download of the GitHub package. Each library will be introduced with the hardware it's related to.Īdd-On Libraries that need to be installed for this project:Īll custom project code is in the main Arduino sketch file. Unless otherwise specified, these libraries can be downloaded the usual manner using the Arduino Library Manager. In order to interact with our different peripherals, this project uses several existing Arduino libraries. Powering MAX7219 LED Bars - Power for these can be daisy chained for the first 2 bars, but cascading 3 or more may require running the power directly to each subsequent display bar, but always keep all the signal lines daisy chained. The displays should draw power from the source supply and not through the Arduino which cannot support enough current to run everything without flickering. (these are the pins used by this code, but can be re-arranged, if desired)Īll devices in this build are powered from a +5V source.
It can be wired, and used as illustrated, however, for repeated, practical usage, the construction of a permanent housing, and mechanical trigger interface, is left up to the implementer to develop per their unique setup.

Note on Housing and Mechanical Interface - This project only documents the functional electrical and software configuration. To get up to speed on those basics, there are many great resources from Arduino and around the web, covering them exhaustively.Īll of the components are readily available and can be connected with basic jumper leads or simple conductor and header pin soldering.
ARDUINO WIRE LIBRARY INTERNAL REGISTER HOW TO
It is expected the reader understands how to use the Arduino IDE, connect wires, and program boards. I have endeavored to explain in enough detail that those interested can follow along and understand how everything works, however, understanding all of the software implementation details is not necessary to build and use this project. This project is easy to assemble and use, but involves a lot of different hardware and software concepts and implements some more intermediate to advanced code for Arduino. Use the corresponding sections of the actual sketch code for working snippets. They are only illustrating the general setup and syntax as used in this project for a reference. Code Snippets - Though many of them can be, the code snippets shown in this project are not meant to be cut and paste, fully functional examples. The down side of this, if attempting to adapt for drone racing, is that each racer needs a dedicated gate, but in turn, this also means that the racing object is irrelevant and does not need to communicate its identity. The original application for this controller was slot car racing, as such, the controller was designed expecting a dedicated lane/gate for each racer. The implementation shown here is immediately useable for 1-4 player racing games. The working demo of this project uses two paper clips integrated into a mechanical lap counter to create a simple, yet effective lap sensor. In the presented configuration, the lap sensing input is simulated using buttons, but can be adapted to be used with a myriad of simple, circuit completion, or other type sensing methods that can be implemented in the physical lap gate. The system consists of a main LCD display, a keypad for user input and menu selection, an 8 digit LED lap count & timer display for each racer, and non-blocking audio for UI feedback and playing a unique victory song for each racer. This is an Arduino based project that implements an inexpensive, reliable, race game controller that can be used for timed racing games. gitignore is part of the git versioning management and can be deleted.Īrduino Race Timer and Lap Gate Controller
