1: This project is used to verify the solution verification board design of the voltage comparator LM393 of Lichuang Mall. 2: This project is based on the Lichuang EAD open source hardware platform. 3: This verification board uses a slot-type photoelectric through-beam switch and a photoresistor. The voltage comparator outputs high level through LM393 here. 4: This module is suitable for a variety of microcontrollers as peripheral inputs. The slotted photoelectric through-beam switch can be used for limit switches, speed encoders, etc.. The photoresistor can be used for light brightness detection, and it is equipped with an adjustable resistor pair. Sensitivity adjustment.
