Assume that you are moving towards a complex microcontroller project bundled with blinkers, beepers, and a display panel. To link a standard 16×2 LCD directly with the microcontroller, for instance ...

RFID Module: Reads the UID from an RFID tag/card. If the UID matches the authorized UID, access is granted. Ensure the RFID tag/card UID matches the authorized UID in the code. Use the potentiometer ...

We all know how the free pins microcontrollers are precious. The use of an LCD display in our projects is often unavoidable. In the best case the cost is at least six pin and you'll understand, ...

The I2C (Inter-Integrated Circuit) bus is a synchronous serial communication protocol that allows multiple electronic components (sensors, displays, memories, etc.) to be connected within the same ...

The most difference to the original LiquidCrystal library from Arduino is that this library supports printf() functionality. When using PlatformIO and AVR, to support float you must add following line ...

In this guide, we will create a simple and precise digital clock using the Raspberry Pi Pico RTC DS3231 Module through the Arduino IDE. We will use a 16x2 I²C LCD screen to display the information.
