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 to be >= 10k. Circuit

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 use basic timer as in example below. The example shows how to turn on and off LED_BUILTIN IN 1000ms interval

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 interrupts. Interrupts project on tinkercad Variables used inside the interrupt need to be global and volatile. In order to add

Humans can hear sounds in a specific frequency range: 20Hz – 20kHzEach tone is defined by the sound frequency, below is a full gamma: C D E F G A B C Piezo play melody project on tinkercad How to make Basic piano with Arduino How to play any melody with Arduino Tones are played
