单片机应用——IO控制（一）
原理图
功能简介：芯片上店3s内输出为零。A组逻辑与BCD一致。
A拉低1秒，k输出14s的高后输出低电平并且保持低，A拉低3s（开脚）高1.5s，低2s，高1.5s，一直低；A拉低6s后，A1输出高，高1.5s，低2s，跳转高电平1.5s，一直低；如果A拉低后一直低，K就一直低，（开脚）也一直低 ，A1保持低电平；如果A释放1s后，K端输出14s高跳转为低电平；A释放3s后，（关脚）高1.5s，低2s，又高1.5s后一直保持低状态；A释放6s后，A1输出两次高电平，A1保持低电平。
简单来说：A每次拉低，K先输出14s高，接下来（开脚）闪两次，再A1闪两次，之后K保持低电平；
A释放，K输出14s高，（关脚）闪两次，再A1闪两次，之后全部输出保持低。
