Led pinout download10/21/2023 PinMode ( 8, OUTPUT) // to set the OUTPUT mode of pin number 8.ĭelay(1000) // 1 second = 1 x 1000 millisecondsĭelay(500) // 0.5 second = 0.5 x 1000 milliseconds Open the IDE and start with the coding, which is given below: We need to install the Arduino IDE, to begin with the coding, which is already discussed. It also displays the LED and resistance connected to the board. The structure clearly shows the pinout of the UNO board. Usually, the value should not exceed the allowable forward current. We can use other value of resistors as well, depending on our circuit requirements. We can use a resistor of any value upto 470 Ohms. We can also use other types of Arduino boards, such as Arduino Zero, Arduino Micro, etc. We can use any version of the UNO board, such as UNO R3, etc. The components used in the blinking of an LED are listed below: Here, cathode is the negative terminal and anode is the positive terminal. The long terminal is called Anode, and the shorter terminal is called Cathode. The two terminals are called as Cathode and Anode. Structure of LEDĪn LED is a two-terminal device. The LED will work as a simple light that can be turned ON and OFF for a specified duration. In this project, we will connect the LED to the digital pin on the Arduino board. It is also used as an ON/OFF indicator in different electronic devices. LED (Light Emitting Diode) is an electronic device, which emits light when the current passes through its terminals. It is the simple basic project created using Arduino.
