描述

大家好，我是 Sarvesh。幾天前，我想玩一些復(fù)古游戲。所以我把它們安裝在我的電腦上。但我只能用我的電腦鍵盤玩，這并沒有給我童年時(shí)代的感覺。所以我決定為我的 PC 構(gòu)建一個(gè)可以玩舊游戲和新游戲（不是全部）的游戲手柄。我使用了一個(gè)舊的游戲控制器并對其進(jìn)行了修改以創(chuàng)建這個(gè)很棒的游戲手柄。這是一款用于 PC 的有線游戲手柄。它可以用來玩模擬器和PC游戲。此外，操縱桿還可以用作 PC 的鼠標(biāo)。游戲手柄使用 Arduino Pro Micro 進(jìn)行控制。

第 1 步：電路圖和按鍵映射

?

?

根據(jù)上面給出的電路圖（第一個(gè)圖像）連接所有組件。

我建議首先檢查所有連接并在面包板上工作。

按鍵映射：

我實(shí)際按鈕放置的布局也顯示在上面（第二張圖片），讓您清楚地知道哪個(gè)按鈕位于何處，它使用什么標(biāo)簽編程以及它向計(jì)算機(jī)發(fā)送什么字符。

第 2 步：Arduino 代碼

現(xiàn)在下載代碼并安裝 mouse.h 和 keyboard.h 庫。將代碼上傳到您的 Arduino。

您可以從下面復(fù)制代碼。

第 3 步：切割、繪畫和焊接

首先根據(jù)游戲手柄的尺寸切割 PCB 并將按鈕和操縱桿模塊對齊。

然后用你選擇的顏色給游戲手柄上漆。

現(xiàn)在將按鈕和操縱桿焊接到通用 pcb 上。

然后借助一些強(qiáng)力膠將限位開關(guān)固定在它們的位置。

焊接其余組件并進(jìn)行最終測試。

我附上了下面的圖片以供參考。

這是最終項(xiàng)目的樣子。
