ESP32 Weather Station
electronicguru0007 Aug 23,2022
In this project, we will learn how to create a weather station, which will display reading from a BME280 module and live weather data from OpenWeatherMap API in a webserver. The device will get temperature, humidity, barometric pressure, and altitude from the BME280 sensor and external temperature, humidity, weather condition, and sunrise and sunset from OpenWeatherMap API. We can see those reading in a web browser. BME280 Temperature, Humidity & Pressure SensorThe BME280 is a...

STM32F4 Black-pill: WiFi shield (WiFiNINA)
Mischianti Aug 22,2022
STM32F1 Blue-pill: WiFi shield (WiFiNINA)Complete tutorial here.First of all, read the article “STM32: use WiFiNINA with ESP32 WiFi Co-Processor”, where there are all the basics to understand this shield usage better.For me, It’s very important the network connection and network limitation on STM32 It’s very tedious. Adafruit offers a solution, but I think that a shield It’s more usable.So I design a shield to add WiFi to my STM32F1 blue-pill.For me, It’s very important the network connecti...

Esp32 Home Automation
electronicguru0007 Aug 21,2022
There are relay modules whose electromagnet can be powered by 5V and with 3.3V. Both can be used with the ESP32 or ESP8266 – you can either use the VIN pin (that provides 5V) or the 3.3V pin.Additionally, some come with built-in optocoupler that add an extra “layer” of protection, optically isolating the ESP boards from the relay circuit.The second set of pins consists of GND, VCC, and JD-VCC pins. The JD-VCC pin powers the electromagnet of the relay. Notice that th...

Using RT-Thread Studio To Control ESP32 With STM32F469 Disco
abouhatab Aug 19,2022
BackgroundLong before TED Talks became popular, there was a radio program that tells the story of how our culture is formed by human creativity. That radio program, Engines of Our Ingenuity, has been featured in one of my previous projects, If The Allegations Are Not Legit, You m. AWS. t EduKit. We wanted to make a device that plays episodes with more screen space to allow for user control and for that we used STM32F469 DISCOVERY board. We didn't just want random and forward/backward n...

110/220VAC Opto-Isolated Zero Cross Detector Module for DIN Rail Carrier Mount with 3.3V or 5V Output - Ideal for Arduino, ESP32/ESP8266
TStar Aug 15,2022
This module detects the zero cross point of an AC supply and outputs a 3.3V or 5V square wave signal pulse of 1ms every time the zero point is crossed. For a 50Hz supply this pulse would be sent 100 times per second. This is ideal for micro-controller projects which require accurate synchronization with the AC supply, such as for controlling triacs to perform phase-angle control for light dimming or heater control. The AC side of the circuit is optically isolated from the DC side, providing impo...
