Magnetic control lamp simplified version

Overview

Working principle:
The polarity of the magnet is detected by the CC6205 Hall sensor. CC6205 is a low-power, bipolar latch Hall sensor with an operating voltage of 2-5V. It is powered by a CR927 button battery. When the south pole of the magnet approaches, CC6205 outputs a low level, and when the north pole of the magnet approaches, CC6205 outputs a high level. Connecting the cathode of the LED to the output pin of CC6205 can realize the magnetic control function. When the south pole of the magnet approaches, the LED lights up, and when the north pole of the magnet approaches, the LED goes out.
