An Atmega library for multiple HD44780 LCDs
https://www.electronics-lab.com/news/atmega-library-multiple-hd44780-lcds/
Davide Gironi has posted an I2C multiple HD44780 AVR Atmega library: This library implements a driver for HD44780 lcd connected through PCF8574 port expander. Data is transmitted using only 2 wire over i2c with the PCF8574. This library can drive up to 8 LCD concurrently. Lcd driver is based upon Peter Fleury’s lcd driver HD44780 […]

How to Scroll a single LCD line – Arduino
https://www.electronics-lab.com/news/scroll-single-lcd-line/
R Jordan Kreindler show us how to scroll a single line on a LCD display. The Liquid Crystal Library has two quite useful functions scrollDisplayLeft() and scrollDisplayRight(). These functions scroll the whole display. That is, they scroll both lines on a 1602 LCD and all four lines on a 2004 LCD. What we often need […]
1.8″ DIY Photo Frame using and Arduino Nano and a ST7735 Color TFT display
https://www.electronics-lab.com/news/1-8-diy-photo-frame-using-arduino-nano-1-8-st7735-color-tft-display/
In this video educ8s.tv is going to show us how to use the SD card slot of the popular 1.8″ Color TFT display which uses the ST7735 driver. Then we will save some bitmap images in the SD card and we will display them on the display. In other words, we will build a simple […]

In this video we learn how to drive the new, low cost big, 3.5″ Color TFT display for Arduino Uno and Mega. For the written tutorial please check here. A few weeks ago, I discovered this promising new display on Banggood.com and thought that it might be useful in some of our projects. The price […]
6 Digit Serial Display Driver with CAT4016
https://www.electronics-lab.com/news/6-digit-serial-display-driver-cat4016/
6 Digit serial display project has been designed around CAT4016 IC from ON semi. The CAT4016 is a 16 channel constant current driver for LED billboard and other general display applications. LED channel currents are programmed together via an external RSET resistor. Low output voltage operation on the LED channels as low as 0.4 V […]
