我做了一个由任天堂 wii nunchuck 控制器控制的 led 眼球。
目次
配置
微控制器使用 arduino uno
68个 led (Neopixel) 用于眼球。
led 用双面胶带固定在碗上, 并按以下顺序连接。
使用 wii nunchuck 在控制器
wii nunchuck 设置
这里有一个图书馆, 连接 wii nunchuck 到 arduino。
https://github.com/todbot/wiichuck_adapter
wii nunchuck 的布线方法指的是以下内容。
- Wii VDD 引脚到 arduino 3.3 v 引脚
- Wii GND 引脚至 arduino GND pin
- Wii SDA 引脚到 arduino A4
- Wii SCL 引脚到 arduino A5
arduino ide 代码
我编写了 wiichuck 适配器库的 wiichuckdemo. ino 示例作为参考。
用操纵杆移动眼睛和眼睑, 用 z 按钮改变瞳孔的颜色。
