Review: Great Arduino-compatible board – perfect for DIY and aquarium projects - I bought the ELEGOO UNO R3 for a DIY project to automate water refilling in my aquarium and to control automatic dosing of plant supplements. The board worked flawlessly and was recognised instantly in the Arduino IDE. Programming was straightforward, and compatibility with libraries and sensors made the whole project much easier. The board feels well made and stable in operation, even when running continuously. Having plenty of I/O pins allowed me to connect multiple sensors and relays without any issues. The included USB cable is a nice touch, making it ready to use straight away. Overall, this is an excellent Arduino-compatible board that’s ideal for DIY projects, learning, and automation tasks. Great value for the money and highly recommended. ## Features - Full IDE Compatibility: Seamlessly works with the official Arduino IDE for easy programming.
