Learn electronics, coding, and projects — step by step.
In this article, I will demonstrate how to use an RFID module such as the MFRC522 with ESP32 using MicroPython programming language.
In this article, I will discussed how you can use ESP32 BLE capability using MicroPython. Bluetooth Low Energy or BLE is very popular on most devices today because of its low power consumption. That is achieve by constantly switching to sleep mode then once in a while wakes up to process Bluetooth functions. With its low power requirements, it is best suited for battery operated applications.
In this video, we will learn how to interface and use SD Card with ESP32 using MicroPython programming language.
In this article, I would like to share to you on how to create this simple yet cool project using a single 8×8 dot matrix module to display a binary clock – a clock that is represented using binary numeric system.
In the previous tutorial, I demonstrate the use of MQTT protocol by sending DHT sensor readings to Thingspeak as MQTT broker while the ESP32 serves as MQTT client. The act of MQTT client sending data to MQTT broker is called MQTT publish. Now in this tutorial, I will demonstrate the other direction of MQTT communication which […]
