Learn electronics, coding, and projects — step by step.
In the previous tutorials we learned to create web server both as station mode and access point mode using socket connection. And in last video, we use a DHT sensor for displaying measurement readings in simple web server similar to a weather station. While displaying sensor values, we discovered the necessity of constantly updating the […]
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.
I have this little tiny microcontroller lying around for some time in my bins. I purchased this out of curiosity but not able find time to try. Yesterday, I saw it again and I decided to give it a try. So here it is. For the datasheet you may refer to: https://ww1.microchip.com/downloads/en/DeviceDoc/Atmel-2586-AVR-8-bit-Microcontroller-ATtiny25-ATtiny45-ATtiny85_Datasheet.pdf For the schematic […]
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 […]
