Summary of the Circuit

This circuit is designed to control three LEDs (red, green, and blue) using an Arduino UNO microcontroller. Each LED is connected to a digital output pin on the Arduino (D13 for red, D12 for green, and D11 for blue) and is in series with a 200 Ohm resistor to ground. The purpose of the circuit is to rapidly turn the LEDs on and off in a sequence, creating a blinking effect.

This code is designed to run on an Arduino UNO microcontroller. It initializes three digital pins as outputs to control the red, green, and blue LEDs. In the main loop, it turns on all the LEDs for 100 milliseconds, then turns them off for another 100 milliseconds, creating a blinking effect.
