Before we do anything, let us first check if your Arduino Uno is properly working. To test the board let us use the Blink example in the Arduino website. First download and unzip the open-source Arduino software(IDE) into your computer. Once the installation is complete, open the Arduino interface and navigate to the menu. Click File > Examples > Basics > Blink. Once the blink sketch is open, click Verify and then Upload. The onboard yellow led lights will turn on and off repeatedly as shown above. If everything works well, then give yourself a tap on the back, you just successfully tested a working Arduino board. To step up the excitement, let us now start making an external blinking LED using the materials, diagrams, codes and procedures as follows:
Arduino R3 UNO
Code # A:
Arduino Blink Version
modified by J.B. Wylzan */
Actual Layout :
1. Insert one end of the white wire to GND (above pin 13)
2. Insert the other end of the white wire to the breadboard.
3. Insert one end of resistor next to the white wire as shown above
4. Insert the other end of the resistor next to the shorter leg of the LED
5. Insert one end of the red wire next to the longer side of the LED.
6. Insert the other end of the red wire into pin # 8 as shown above.
7. Run the Arduino Interface
8. Select File > New
9. Copy Code #A above
10. Paste Code #A
11. Click File > Save
12. Click Verify
13. Click Upload
14. Your LED is now blinking On and OFF
long d = 0;
d++; // blink the led 10x
