Introduction: How to BLINK Led With Arduino in Single Step

Hello friends in this instructables we are telling about a basic project with arduino

ie., how to blink an led with arduino

Step 1: Parts Required

1.arduino uno r3 (microcontroller) - 1 arduino

2.led - 1 (optional)

3.resistor(100ohm) - 1 (optional)


5.connecting wires

Step 2: About Arduino

Arduino is a computer hardware and software company, project, and user community that designs and manufactures microcontroller
kits for building digital devices and interactive objects that can sense and control objects in the physical world. The project's products are distributed as open-source hardware and software

As we can see in the image there are digital pins I/O(0to13) , analog pins A0 to A5 , power setup ie., gnd,5volts,3.3volts,dc jack,usb which is used to upload the code and also used as power supply to the arduino

Step 3: Procedure

Intially connect the circuit as shown in the figure , then upload the program that is provided in the attachement ,

if we dont have an led also we can blink the led which is inbuit led wth arduino that is near to 13 pin as shown in the figure it will be blinking when we upload the code

you can find the code IDE at files-> examples->basics->blink

comments me if you have any doubts

welcome to the family of arduino :-)
