So in this tutorial, we will make a simple circuit with the help of the 433 Mhz RF module that requires no microcontroller and no code to light an LED wireless. Note : If we search the web for 433MHz ...

The hardware is consists of an Arduino microcontroller (here an Arduino Uno R3) and a pre-wired soil moisture sensor module. The soil moisture sensor module , built around the LM393 comparator, gives ...

Arduino project for receiving and (in the future) transmitting signals using a 433 MHz RF module. Currently, this repository contains code for a 433 MHz signal receiver , which allows reading signals ...

Here, Arduino’s (Uno R3) A4 (SDA) and A5 (SCK/SCL) pins are used for the I2C control, and the module is 3.3 V powered by the Arduino itself. It seems that external pull-up resistors for I2C lines are ...
