This is tutorial number 1 from our series of Arduino tutorials and in this part I will talk about blinking an LED using the one already available on the Arduino Uno board or using an external LED to ...

For the first sketch, let's blink an LED and then extend it to blink multiple LEDs alternately. Before the software part, let's first set up the circuit to connect the LED to the Arduino.

I made this Arduino 8 bit binary led counter as a solution for one member from Arduino forum. He asked if somebody can make a project that displays a decimal number in 8 bit binary format using 8 leds ...

If you are just learning how to do Arduino projects or want to start, here are six fun and easy projects you can try that are perfect for beginner programmers.

That article discussed the use of memory-mapped LED control registers, buffers, and a clock source, all used to blink an LED without burdening the microcontroller code with the task.

He found himself often rewriting very similar Arduino code for each one of these installations, and eventually decided he could save himself (and all the other hackers in the world) some time by ...
