About this project

Code debugging session days before Arduino Day Sevilla 2019

Open days event organized by Sevilla Maker Society on March 16th:

https://www.meetup.com/es-ES/Maker-Society/events/259416356/

In the basic game mode, the only one implemented for the moment, is that the speed of the car is proportional to the pulsations of the control button, in the ascent ramps must be pressed more quickly to compensate for the effect of simulated gravity, but we have thought of options for other "arcade" mode in which on the track will happen things that will make you have to make decisions, fuel consumption, expenditure of tires, and must enter to boxes by a way of service and solve certain challenges to be able to continue the race. At the beginning each car is represented by two leds, and in each complete turn is increased by one led.

This project was done in a few days for the Arduino Day 2019 event, so it can be considered a work in progress, but here is shared the current status of the project, each should look for the materials available. The code is made dirty and fast, so it can also be improved.

Attitude maker and good luck!

We want to see what hacks you do with our project !!
