An LCD can be made to connect to a microcontroller using two wires with the aid of the I2C interface which includes pins for an SPI interface version for flexibility. The I2C LCD interface is used ...

Abstract: This paper presents the design of an Intellectual Property (IP) that converts a serial output signal into a parallel output signal for a liquid crystal display (LCD). The IP is intended for ...

This articles describes how you can use I2C (TWI) communication, Arduino and temperature sensors to measure 3 different temperatures. It can be very helpful when you want to measure the outside, ...

Today, We will review the Cytron Maker Uno RP2040 development board combining the Arduino UNO form factor with the Raspberry Pi RP2040 microcontroller that makes it programmable with the Arduino IDE ...
