Thanks to the Arduino Uno R3, which is a microcontroller, it allows you to realize your smart home systems, robotic projects, musical instruments and many similar electronic projects. Uno R3 Arduino (CH340) entries using remote controls, buttons, and you can connect different kinds of sensors, robotic mechanisms by achieving these inputs and outputs according to the data from electronic, motors, speakers, relays, lights, and any data obtained via Ethernet or WiFi and indicators change according to the input values you typed on the internet that you can control programmatically.
