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 ...

Austrian firm Controllino has based its programmable logic controllers (PLCs) on Arduino modules. This is an example of how so-called “maker” open source development platforms are now finding ...

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 ...

Hi, I'm Bill. I'm a software developer with a passion for making and electronics. I do a lot of things and here is where I document my learning in order to be able to inspire other people to make ...

By applying 12 volts to a pair of pins and connecting another 5 wires to an Arduino, it’s possible to drive as many of these Nixie modules as you’d like.

He put it all together on proto-board, although soldering the FM radio module was a bit tricky. The Arduino code is quite simple, and available for download (zip file).

“By incorporating RS485 connectivity, the Arduino Uno SPE Shield becomes a tool for upgrading RS485 legacy systems or integrating modern technologies with current infrastructures, creating a bridge ...

Last Updated: 7/27/18 This Arduino module takes past circuits and codes, and applies them to a new program called Snap4Arduino. Snap4Arduino allows us to program an Arduino board in an environment ...

The Pressure Sensor Module incorporates a material called Velostat with the Arduino. This material adds more resistance when more pressure is applied to the material. This module also uses the RGB LED ...
