Learn electronics, coding, and projects — step by step.
In this article you will learn to configure ESP32 wifi as Access Point. You will also learn to create a web server hosted on it.
In this article, we will learn how to create a web server hosted in ESP32 using MicroPython language for controlling the state of GPIO pin. This can be applied for controlling a relay which is popular in home automation projects.
In this tutorial, we will tackle on how to interface SIM800L GSM module to ESP32 in MicroPython. CIRCUIT DIAGRAM INSTRUCTION Connect SIM800L Rx pin to ESP32 GPIO 16 (Tx2). Connect SIM800L Tx pin to ESP32 GPIO 17 (Rx2). Connect the SIM800L VCC pin to external positive terminal. In this tutorial, I use external power supply […]
In this tutorial, we will learn to use the UART peripheral of ESP32 in MicroPython. UART is useful for interfacing devices such as DF Player Mini mp3 player module, SIM800L gsm module, HC-06 bluetooth module, and etc which basically needs serial communication as mode of control. ESP32 has 3 hardware uart serial ports available which […]
In this video, we will learn how to use the HC-SR04 ultrasonic sensor in MicroPython. With ultrasonic sensor, it can be use for measuring distance or it can be use for sensing an object. CIRCUIT DIAGRAM INSTRUCTION Connect the HC-SR04 VCC pin to ESP32 VIN pin. The HC-SR04 needs 5V, trust me I already tried […]
