If the LED doesn't turn on, it might just be connected the wrong way around. Connect the ground pin to the longer leg and pin 23 to the other leg and try again.

A MicroPython application written for an ESP32 microcontroller, used for reading environmental data from DHT22, BME280, SHT30, ENS160, or PMS5003 sensors, or distance from a VL53L1X, and sending the ...

Modern microcontrollers, such as an ESP32, are so powerful that they can be programmed in MicroPython – thanks to the powerful libraries, this allows you to quickly achieve a finished project. With ...

He eventually settled on a “bottum-up” approach to build a library for the platform, rather than implementing MicroPython directly as a firmware image for the ESP32.

The global shift toward electric vehicles (EVs) has created a critical need for efficient and sustainable renewable-powered EV charging infrastructure. This paper presents an innovative ESP32-based ...
