The Design and Simulation of Sit-Up Counter Based on MCU

Our country’s economy and people’s material life level rapid ascension, people also pay more and more attention to personal health in today’s busy society. We do not have the time and space to do strenuous exercise. You can squeeze in some sit-ups during the AD breaks on TV in the evenings. To get a better count, this work designs a sit-up counter based on MCU. This design put computer software and hardware technology as one solution, using 51 SCM as the control core, achieve the automatic counting crunches. Specific processes include start, end control, real-time display the count value, tip end of the test, etc. This design has a simple structure, functional, practical, and high reliability.
