This PCB design schematic depicts a simple LED circuit. Here's a description: The circuit consists of: Power Source: The circuit is powered by a DC voltage source. Resistor (R1): A resistor is connected in series with the LED to limit the current and prevent it from exceeding the LED's maximum rating. LED: The LED is the main component that will illuminate when the circuit is powered. Switch: A switch is included in the circuit, allowing the LED to be turned on or off. This basic setup is commonly used for educational purposes or simple indicator lights in electronic devices.
