聲控 LED 面罩連接說明

防范措施：

制作聲控?zé)裘嬲謺r，電路焊接時請小心，以免被焊機燙傷皮膚！請正確連接電路并選擇好的充電寶。電路短路和電流輸入不良可能引起事故！聲光口罩是要貼在臉上的，所以口罩面料的選擇很重要，請選擇防火面料！最后請小孩子在大人陪同下制作。

所需工具：

焊接

烙鐵

織物膠水或針線包

護目鏡

膠帶

剪

可選有用的東西

熱縮管（電工膠帶可以在緊要關(guān)頭使用，但熱縮管很好）

數(shù)字萬用表（用于確保您的連接正確且電子設(shè)備正常工作）

焊墊

阿杜諾納米

零件

LED 矩陣 8x8 WS2812B

麥克風(fēng)max4466

阿杜諾納米

330Ω電阻

24號線

熱收縮

5V移動電源

KCD1開關(guān)

生產(chǎn)

1、安裝庫文件：打開Arduino開發(fā)軟件中的“工具”-“庫管理器”，然后搜索Adafruit_NeoPixel、Adafruit_NeoMatrix、Adafruit_GFX_Library，然后安裝這三個庫

2.選擇開發(fā)板為Arduino Nano，這個是選對了。

?

3.選擇處理器為ATmega328P(Old Bootloader)，這個是選對了。

?

4、然后選擇端口，這個端口要和你在設(shè)備管理器里看到的一樣，這樣你就可以把代碼燒進開發(fā)板了。
