Arduino Blink LED Circuit To connect an LED to an Arduino, you need a resistor in series with the LED. This is to limit how much current the LED pulls out of the Arduino pin. The value isn’t crucial but should be between 220 Ω and 1000 Ω. Connecting On a Breadboard Here’s how...

Begin with Tinkercad: Its drag-and-drop simplicity is perfect for mastering basics like LED blinking or button inputs. I started a workshop with a Tinkercad traffic light circuit—10 minutes in, everyone was hooked. Graduate to Wokwi: Once comfortable, try Wokwi for complex boards like ESP...
So what is happening in this circuit? I've assumed that themicrocontrolleris running on a Vcc of 2V which is not enough to illuminate white LED D2. At least 3V is required to make it glow. To boost the voltage on the LED a square wave is generated in the microcontroller by software...
