Description<\/p>\n
The lab was about the basic task of blinking an LED.\u00a0I connected the output pin 13 and the ground pin to the breadboard. Next I placed a resistor (220 ohms) on the breadboard and connected it to the jumper cable connecting output pin 13. The long leg of the LED was connected to the resistor and the shorter was connected to the jumper cable connecting to the ground pin. I wrote a code to vary the duration of LED blinking using a for loop. This reminded me of the lights we have up at diwali\u00a0(festival of lights) where a similar random repeating set of LEDs are lit.<\/p>\n

\n * Materials:
\n *
\n * 1 Arduino Uno R3
\n * 1 Breadboard
\n * 1 LED
\n * 5 jumper cables
\n * 1 USB power cable
