LED Blinking with Arduino Uno
LED Blinking with Arduino Uno
ARDUINO
UNO is an ATMEGA controller based board designed for electronic engineers
and hobbyists.
Arduino based program
development environment is an easy way to write the program when compared to
other environment development programs.
Components Required
Hardware: Arduino uno board, connecting
pins, 220Ω resistor, LED, breadboard.
Circuit Diagram and Working Explanation
Here
we are going to write a program to blink an LED for every 500ms. In arduino uno, a LED will be already
designed at the pin13, but we are not going to use it. Here we are going to connect an indicating LED to
PIN0 through a current limiting resistor.
The
controller in arduino is already programmed to work on external crystal. So we need not to worry about fuse bits or
anything.
The arduino works on 16Mhz
crystal clock, which is already embedded in the board.
