This project is a smart water dispenser system built using an ESP32 microcontroller, MicroPython, an ultrasonic sensor, and a relay. The system automatically dispenses water when an object is detected ...

This is an asynchronous ESP32 ... using MicroPython Code. We will first interface the Sensor with ESP32 only and check the temperature and humidity reading in Shell Window. Similarly, we will add ...

In this tutorial, we will interface an ultrasonic sensor with the pico board and we are going to measure the distance of an object and then we will display the distance on the OLED display module ...

The HC-SR04 ultrasonic sensor has a ... you need to use the I2C pin which is the IO21 and IO22 of the ESP32 module. That's all for the connection process; the hardware image below will give you a ...
