This basic circuit illustrates how for build an electrical circuit by a ESP32 S3 microcontroller plus the 1k Ω impedance. By positioning two impedances in sequence, you are able to reduce a voltage level into an value http://theengineerstore.in/products/waveshare-esp32-s3-microcontroller-2-4-ghz-wi-fi-development-board-dual-core-processor-with-frequency-up-to-240-mhz
