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 ...

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 ...

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 relay module will need 5V from Arduino to power up and will get input from four different digital pins of the Arduino. Now let’s connect the relay module to your home appliance. Take the positive ...

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 ...
