1. Selection of pull-up resistor for MCU You can see that when the resistor R1=10k in the reset circuit, RST is high level, and when R1=50, RST is low level. It is obvious that when R1=10k, it is wro
Traditional sensing technologies have been used to solve challenging problems such as people counting, motion detection, industrial area scanning, and robotics to detect objects and avoid collisions.A
