ESP8266 Remote Relay
Reboot Oct 23,2022
This pcb has a WeMOS D1 Mini with ESP8266 to control the on board relay.Control of the relay can occur wirelessly, and the ESP8266 UART pins are also available on a header to optionally allow an external RS485 or bluetooth module to be used.The Github project uses ESP-NOW to communicate between this relay control board and another ESP8266 board that uses a current transformer: https://www.pcbway.com/project/shareproject/SCT013_Current_Monitor_for_ESP8266_cc7ccd2e.htmlWhen the current transformer...

Picoclick C3 - most advanced IOT-Button
König Oct 21,2022
The Picoclick is a tiny device which can be used as an IOT-Button. It is a one-button-device which let's you control different stuff in your smart home or the internet of things. A basic example is to toggle a light bulb by a button press. Moreover the Picoclick-C3 can be used as a mini development board, because it comes with an FPC extension port where other hardware can be connected to - even I2C is possible.The Picoclick is an ultra low power device, it only consumes 2μA of current in idle s...

ESP32 IoT Relay Control
ELECTRONOOBS Oct 20,2022
This PCB here that I call NOOBIX gives you full IOT control for anything. A lamp, a fan, your stereo speakers, your printer, anything you want. With a simple online push of a button from anywhere in the world, you can turn ON or OFF any device that works at 220V AC. This project is based on a previous tutorial where I show you how to use the ESP32 and the HTTP library in Arduino IDE. The PCB has its own voltage regulator from 220V AC to 12V, 5V and 3.3V DC, it has a solid state relay to control ...

How to make RMS to DC Converter using IC AD736
electronicguru0007 Oct 17,2022
A True-RMS or TRMS is a type of converter which converts RMS value to equivalent DC value. Here in this tutorial, we will learn about true RMS to DC converter, how it works and how measurement methods can affect displayed results.The IC AD736 has few functional subsections like the input amplifier, full-wave rectifier (FWR), RMS core, output amplifier, and bias section. The Input amplifier is constructed with MOSFETs, so it is responsible for the high impedance of this IC.After the input am...

Arduino NANO 33 IoT SPI Flash memory shield
Mischianti Oct 13,2022
Like the Arduino MKR WiFi 1010, the NANO 33 IoT doesn’t have Flash memory to store data. I wrote an article that explains how to interface these kinds of memory, “How to use external SPI Flash memories“, and I’d like to simplify the process of adding these chips, so I created another simple PCB shield to add external SPI Flash memory in the fastest way.The configuration is the same as the examples already posted.Read the article "Arduino NANO 33 IoT SPI Flash memory shield" to have more informat...
