我做了拼图计时器使用触摸屏 tft 显示。这将测量拼图完成前的时间。
目次
宪法
用于 arduino uno 的触摸屏显示屏蔽用于显示时间, 当拼图完成时计时器将停止。
部分
- 微电脑 arduino uno
- 触摸屏液晶显示屏蔽 ul024tf
- 木制拼图
- 铜箔胶带
处理拼图
通过将铜箔胶带贴在木制拼图的背面, 当拼图完成时, 它将变得导电。
- 在框架上钻两个孔, 让它通过导体, 并将其焊接到铜箔胶带的电极上。
- 用铜箔覆盖拼图的侧面和背面, 这样两个点完成后就会进行。
触摸屏 tft 显示屏蔽
司机是伊拉克9325。320 x 240 像素。我把它作为秒表来衡量完成拼图的时间。
arduino ide 程序
我使用了以下 arduino 库。我创建了一个基于示例程序 tft痛. ino 的程序。
在 uno 中插入显示屏蔽, 并将拼图的两个极接线连接到 a5 引脚, 将另一个连接到 gnd。当触摸屏上的 “开始” 被推, 计时器启动, 拼图完成, 秒表停止时, a5 进行到 gnd。
