In this example we will change LED brightness based on the potentiometer position. We will use map() method to adjust 10 bit input values to 8 bit analog PWM output values.Remember that potentiometer’s resistance needs

We can delay execution of some functions by using delay() method. There is one significant drawback, delay() ,method pauses the whole system for given time. In most cases it is unacceptable.That’s why it’s better to

How to connect multiple LEDs on breadboard to the Arduino pins?

Hardware interruptsOn Arduino Uno there are only 2 pins that can handle interrupts (2 and 3) by default. Interrupts has to be quick in execution. Methods like delay(), Serial, millis() can not be used with
