Arduino UNO
An open-source development board based on the ATmega328P microcontroller, featuring 14 digital I/O pins and 6 analog inputs. It comes with the Arduino IDE and library ecosystem and is widely used in introductory embedded and maker education projects.

Compared with the classic UNO, the Arduino UNO R4 WiFi adds peripherals such as a CAN bus, a 12-bit DAC, and an operational amplifier, while GPIO voltage remains 5V, making it compatible with most traditional shields.
On Reddit, a student majoring in control and robotics engineering showed an animated electronic eye project driven by an Arduino UNO, paired with a browser-based block programming tool.
The hardware of this electronic eye project consists of two servos, an Arduino UNO, and a 3D-printed frame, with one servo each for left-right rotation and up-down rotation.
The Arduino UNO is an open-source development board based on the ATmega328P microcontroller, with 14 digital I/O pins and 6 analog inputs.
A servo's instantaneous current can reach over 1A when stalled or rapidly reversing direction, and when driving multiple servos at the same time it is best to power them separately to avoid overheating or resetting the UNO's onboard regulator.
