The WiFi Relay Shield is an Arduino compatible module that provides an easy way to control high voltage loads thanks to 4 independent channels equipped with photo-coupled mechanical relays ...

Currently the arduino sketch broadcasts its IP address every 10s on UDP port 8981. Eventually it will use SSDP (which is supported by the Hubitat driver framework). The default MAC address should give ...

I just received my RC522 RFID reader and made this simple Arduino access control system that uses the reader, a buzzer for the alarm and a relay shield for the security system. The relay can be used ...

Mayhew Labs have unveiled a new DAC add-on board they have created for the Arduino platform in the form of the Extended DAC Shield that takes the form of a high-speed, precision, eight channel, -10V ...

Arduino UNO SPE Shield adds Single Pair Ethernet (SPE) and RS485 to Arduino UNO and compatible boards, notably the Arduino UNO R4, via a Microchip LAN8651 SPE controller. Single Pair Ethernet relies ...

When developing electronic projects, the power supply is one of the most important part of whole project and there is always need of multiple output voltage power supply. This is because different ...

The Arduino GIGA Display Shield is a 3.97-inch RGB touchscreen display designed for the Arduino GIGA R1 WiFi board introduced a few months ago with an STM32H7 dual-core Cortex-M7/M4 microcontroller ...

So, what do you do when your Arduino project needs to operate in a remote area or as a portable device? There are LiPo battery shields available, and although they may work well, recharging requires ...
