摘要

We have finished the research and development of multi-step temperature controller. The temperature range of the controller is adjustable from 0° to 300°, the time during which the temperature keeps a fixed value also is adjustable from 0 to 999 minutes. It communicates with computer by serial port RS232. To implement such control, we need to use keyboard to input the temperature and the time expected. The circuit diagram is shown as follows.
