1. Two Python Development Paths The ESP8266 runs Python mainly through two methods; understand the differences before getting started: MicroPython Firmware: Burn a lightweight version of Python directly into the module, allowing it to run Python code independently (suitable for local control); Remote Control: The ESP8266 runs a server, and a computer/mobile device sends commands … Read more
Project Name: True Zigbee Door Sensor Project Author: Falling Flowers, Clear Breeze Introduction I want to check the home’s environmental data, such as temperature, whether the door is closed… Zigbee sensors can meet my needs! However…the Zigbee sensors on the market are quite expensive! Their functions are also relatively simple! So I immediately decided! To … Read more

STM32 vs Arduino: Why Does Your LED Always Fail to Light Up? In recent IoT projects, I have used various mainstream development boards and found differences in the drive levels of their onboard LEDs. This is documented for reference. For example, the onboard LEDs of Arduino Nano (D13), Arduino Uno (D13), and ESP32 (D2) are … Read more
In today’s rapidly developing Internet of Things (IoT) landscape, WIFI chips serve as critical components connecting devices to the internet, making their selection crucial for project success. Key Factors in Selecting WIFI Chips When choosing a WIFI chip for secondary development, the following key factors must be considered: 1. Memory Resources: The size of RAM … Read more
In the previous article, we used the ESP8266 (“Sound and Light Guardian”: 51 Microcontroller for Energy-Saving Lighting “Guardian”), today we will first introduce the ESP8266 separately, and then implement the design to control the fan wirelessly (ESP8266). As a pioneer in the Internet of Things (IoT) field, the ESP8266 wireless module has become one of … Read more
