ESP32 - pin requirements and strange behavior you need to know

ESP32 - pin requirements and strange behavior you need to know I will go through the schematic of my smart home sensor. DHT22 (AM2302), LDR, MH-Z19C, HC-SR501, HW-484, MLX90640, BUZZER, IR LED, TSOP 31240, RFM12, HM-10, RM1000. I also talk about choosing the right pin for the right peripheral and how to avoid issues with ESP32 strapping pins. take a look at the schematic: https://github.com/playduino/ceiling-sensor-esp32-poe
