This shield consists of three logical parts: - 1602LCD with HD4780 Dot Matrix Liquid Crystal Display Controller/Driver. - 6 button keypad. - Analog pins, 5V and GND pass through. Additional ...

This project connects a 16x2 or 20x4 LCD Display to an Elegoo Mega 2560, allowing it to display messages or real-time data. The project supports both I2C communication (recommended for fewer wires) ...

In this quick Arduino tutorial I will explain how you can control a relay using the Arduino Board, one 1K and one 10K resistors, 1 BC547 transistor, one 6V or 12V relay, one 1N4007 diode and a 12V fan ...

Arduino enables the fast development of embedded projects. Playing around with Arduino boards is fun, but not the most efficient way to expand your knowledge. Elektor has therefore bundled two of the ...
