Already back 2019 I have developed a working I2C slave implementation where master can read/write to address memory. BTW, this is still not working in Espressif IDE examples or Arduino Wire examples.

O. What is RelayModule Library? If I use it, how easier life will be ? If you have made some Arduino project with Relay Modules, you probably wrote some scattered code for relays. Scattered Code ...

The I2C (Inter-Integrated Circuit) bus is a synchronous serial communication protocol that allows multiple electronic components (sensors, displays, memories, etc.) to be connected within the same ...

Arduino has just launched a “Plug and Make” kit designed for beginners with an Arduino UNO R4 WiFi board, several “Modulino” modules, a “Modulino” base to neatly attach the UNO R4 and modules, and ...

Assume that you are moving towards a complex microcontroller project bundled with blinkers, beepers, and a display panel. To link a standard 16×2 LCD directly with the microcontroller, for instance ...

IN - This pin is also called the control pin because it is used to control the output of the relay. COM - is connected to the device you intend to connect. NC - terminal is connected to the COM ...
