Arduino UNO Circuit Diagram

This image illustrates an Arduino UNO microcontroller board, which is a popular platform for electronics projects and prototyping. Accompanying the main board are three different modules commonly used with Arduino. On the top left, there's a module with SPI communication pins (CS, CLK, MISO, MOSI) along with power (5V, GND), suggesting a memory or sensor interface. In the top center, a sensor module with OUT, VCC, and GND pins is shown, likely for outputting a signal based on a trigger or measurement. To the top right, a module with serial communication pins (TX, RX) and power (5V, GND, RES) is visible, often used for wireless data transfer like Bluetooth. This setup provides a general overview of components typically integrated into Arduino-based circuits.
