利用单片机加控制直流电机，利用P1口，编制程序输出一串脉冲，经放大后驱动小电机，改变输出脉冲的电平及持续时间，达到使电机正转、反转、加速、减速。停转之目的。 可以通过74LS244输入开关量数据来控制小直流电机的转动，实现正转四种转速，反转四种转速及停转。 -The use of SCM in controlling the DC motor

Electronics Design Checklist C) 2003 Hank Wallace This a checklist for electronics designers. The idea is for engineers and technicians to share experiences and create a detailed checklist, which the individual designer can pare down to meet his or her specific needs. There are many details that go into the making of a first-run design success, and this checklist helps prevent Murphy s gremlins from marring an otherwise healthy design.-Electronics Design Checklist C) 2003 Hank Wallace This is a checklist for electronics designers.
