Nowadays, visual indication is a must-have feature for any electronic device, which will make user interaction much easier. There are multiple ways to implement the visual indication, from simple ...

In SAMD Arduino it is possible to map an arduino pin number to a specific pin on a per-board basis? Is the same possible with the ESP32 arduino version? I only see extra variables like D1 = 7; in ...

Recently, we published an entry-level Arduino project with a single seven-segment LED display. Although it’s an amazing DIY project, we noted that most of the readers are looking for more advanced ...

See PCINT pin table at the bottom for more details. Arduino Uno/Nano/Mini: All pins are usable Arduino Mega: 10, 11, 12, 13, 50, 51, 52, 53, A8 (62), A9 (63), A10 (64 ...

This is a simple 0 to 9 counter circuit constructed using Arduino! Here, a common cathode 7-segment LED display is connected to Arduino for displaying the digits. The code (Arduino sketch) allows push ...

A buzzer has two pins, namely positive and negative. The positive terminal is represented by the ‘+’ symbol and negative terminal is represented by the ‘-’ symbol just like an led and a capacitor.
