Schematic diagram (using protues simulation C code written using keil compiler)
Single chip computer renderings:
Mode 0 to display temperature time 123 bits, respectively 10, is a press the corresponding button can achieve the highest or lowest mode 45 shows the highest, the lowest temperature
Part program:
570 lines of the main program + 70 lines of 1602 + 100 temperature sensor display to realize single chip microcomputer temperature time accurate to a very well and have a school, set the value of temperature alarm function accurate to quite a
