To connect an LCD to an Arduino without using an I2C module, you'll need to connect the LCD directly to the Arduino using its parallel interface. Below is a guide to help you achieve this: ...

The receiver is built around Arduino Nano (Board2), Yoda module (YM2), Yoda adaptor (YA2), 2-channel relay module (RM1), and 5V DC power adaptor. Here, the Yoda module acts as an end-node module.

In order to use the ESP-01 Wi-Fi relay module, a programmer/programming adapter is required to program the ESP-01 module (see below). Also it is pretty easy to make your own programmer, or you can ...

To connect your Arduino to the internet, there are two popular options. One option is to use an ESP8266 with Arduino and the second option is to connect an Ethernet module with Arduino. In this ...

Welcome to my quick review of an inexpensive 2-channel 5V relay module controlled via RS485 bus utilizing Modbus RTU protocol. As claimed by some online sellers, this easy-to-get Modbus RTU 2-Channel ...
