Step by step instructions with explanations to construct an LED and piezo buzzer circuit and program it to communicate SOS and other messages in morse code using Arduino ...

Step 6: Understanding The Code. The code of this project is quite well commented and very easy to understand. But still, it is briefly explained below. 1. At the start, Pins of the Arduino are ...

Make sure to connect positive pin(+) of buzzer to Arduino digital pin 7 and negative pin(-) to Arduino GND. In same cases, you may want to connect 100ohm series resistor between buzzer positive(+) pin ...

We burn a C Code on Arduino Nano to tell the microcontroller board how and what operations to perform. Arduino Nano has exactly the same functionality as Arduino Uno but in quite a small size. ... // ...

On the other hand, the Arduino IDE only lets you program Arduino boards with the Arduino programming language, which is based on C++. With that over, let’s make the Arduino blink its internal LED!

Figure an Arduino most matches the "Other" category. To be specific, it isn't an Arduino brand, it is a DigiSpark, but the trouble isn't with the device itself. The problem is with a buzzer. I got ...
