Experimental Arduino library for the I2C LCD display, typical 20x4 characters. The library is inspired by the excellent New-LiquidCrystal library by F. Malpartida. Therefore the interface is kept ...

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 ...

Although there are other ways to do this, [Rod] has decided to write up his method of using two Arduinos and the I2C protocol to expand an Arduino’s IO capacity. As seen in the picture above,… ...

Programming the Matouch_ESP32-S3 demo kit with Arduino/PlatformIO The ESP32-S3 4-inch display board can be programmed with either Arduino or PlatformIO, and we’ll use the demo code provided by ...

As you can see in the schematic all three TC74 sensors have their SDA and SCL pins connected in series to pin A4 and A5 on the Arduino board. The two 4.7K pull-up resistors must be used when using I2C ...

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 ...
