Detect sound direction with Arduino UNO R3, MAX4466 microphones, and an OLED display. Explore FFT analysis for precision. This can be used for real-world applications such as in robotics, security, ...

They’re using a cheap sound sensor module and an Arduino to catch instantaneous photographs, with students caught in the act of popping balloons.

Electronic systems can help the visually impaired. This project combines an Arduino Nano, a TCS34725 color sensor and a buzzer to assist color blind users.

The Arduino Nano and Uno are equipped with very similar processors (the chip that essentially serves as the brain of the board). The Nano features an ATmega328, while the Uno sports an ATmega328P.
