【问题描述】：
我正在使用 Arduino Uno 制作一个基本的体育比赛得分手（壁球/球拍）。
目标是 2 个按钮，每个玩家都有一个按钮，他们可以用它来增加分数。
这很简单，但是如果两个玩家碰巧同时达到 10[score]，他们需要选择是达到 13 还是 15。
我的问题是它在调用 scoreDecide() 函数之前监听最后按下的按钮。
例如，player1 在 9（左键）上，player2 在 10（右键）上。
player1 按下他们的左键将他们最多提升到 10，scoreDecide() 被自动调用为循环识别它是 10/10[score]。
player2 决定按右键，选择 15 作为分数，但实际上它已经选择了左键值，因为这是在调用 scoreDecide() 函数之前按下的最后一个值，这意味着 13 实际上被设置为 target，并且按右键实际上是在增加 player2 的分数。
我的代码如下，到目前为止我已经花了 8 个小时，但我完全是 Arduino 新手，没有运气。
// Squash Scorer, by @MrWigster
// Squash scoring is fairly easy for the most part, however at 10-10 the first player to have reached 10 must decide whether to play until 13 or 15, as the winner must always have a 2 point lead.
// For this reason we need to include logic to let the players choose what score to play until.
