This repository contains Arduino code and documentation for interfacing with an I2C (Inter-Integrated Circuit) LCD (Liquid Crystal Display). The code is designed to facilitate easy integration of I2C ...

Users can simply connect the modules to the Arduino board through Qwiic cables, neatly attach everything together on the provided base, and follow one of the seven projects complete with step-by-step ...

In this review of the Maker Uno RP2040 board with the Arduino IDE we could blink LEDs, control RGB LED lights, press the user button to turn on one LED or make the buzzer output some melody, control a ...

The UNO R4 introduces several hardware upgrades, including an upgraded USB port to USB-C, an increased maximum power supply voltage of 24V, an improved thermal design, a CAN bus for minimizing wiring ...

We might think that an AVR microcontroller – e.g. the ATMega328p adopted by the Arduino UNO boards – has the sufficient number of pins to manage an alphanumeric LCD. In a complex industrial machine ...

Additionally, the Uno features two extra pins, a duplicate of the A4 and A5 pins (meaning, they're internally connected), that you can dedicate for I2C/TWI communication.
