How to Set Up and Program an LCD Display on an Arduino
https://www.electronics-lab.com/how-to-set-up-and-program-an-lcd-display-on-an-arduino/
circuitbasics.com has a nice tutorial on how to use a common Hitachi HD44780 LCD display on Arduino. Many of the functions available are discussed and shown in examples. In this tutorial, I will explain how to set up an LCD display on an Arduino, and show you (with examples) all of the functions available to […]
LED Tester with LCD Display
https://www.electronics-lab.com/led-tester-with-lcd-display/
David @ robotroom.com build a microcontroller based LED tester with LCD display that shows the LED voltage, the current limit in mA, the desired led voltage and the calculated resistor value. The LED tester is based on ATtiny84 mcu which performs all the measurements and calculations and updates the display. Build details on the link […]
Battery Powered Frequency Meter (0 to 20kHz)
https://www.electronics-lab.com/battery-powered-frequency-meter-0-to-20khz/
The circuit is a simple digital frequency meter that is made of a frequency-to-voltage converter and an analog-to-digital display converter that can be operatedfrom a single 9-volt battery. The TC7126 ADC generates the voltage required by the TC9400 FVC with internal regulators. The TC7126 is designed to directly drive a 3-1/2 digit, non-multiplexed LCD display […]
Arduino Distance Meter
https://www.electronics-lab.com/arduino-distance-meter/
Paoson Woodwork @ instructables.com has build an Arduino Based Distance meter using SR-04 Ultrasonic sensors and an LCD display: This a project I’ve been working for some time now. It is a device that shows in a little LCD display the distance to the nearest object it can find, usually the floor, the ceilling and two […]
Home Thermostat With Arduino and LCD
https://www.electronics-lab.com/home-thermostat-with-arduino-and-lcd/
ArisK3 @ instructables.com decided to replace his home thermostat with a DIY one so he build an Arduino based thermostat with big character LCD. Replacing a standard thermostat (SIEMENS-RAA30 16GR) with a self made, arduino-based, big LCD screen is a fun project. Home Thermostat With Arduino and LCD – [Link]

Matthew Filipek from Cornell Univercity has build a nice smart watch with 1.7 inch touch screen, SD card, Bluetooth module and various apps. One of the main inspirations for this project was Jared Sanson’s implementation of a DIY smartwatch (REF 0). With several design iterations, he was able to produce a watch in a very […]
chipKIT Tutorial: Using Nokia 5110 LCD
https://www.electronics-lab.com/chipkit-tutorial-using-nokia-5110-lcd/
Raj @ embedded-lab.com has posted another great tutorial on how to interface a Nokia 5110 LCD to chipKIT board. Today, we will see how to connect a NOKIA 5110 graphical LCD (used in Nokia 5110 cell phones), which is a 84×48 pixel monochrome display of about 1.5″ diagonal in size. The display can be used for […]
Better 3D graphics on the Arduino – ILI9341 LCD
https://www.electronics-lab.com/better-3d-graphics-on-the-arduino-ili9341-lcd/
M Rule @ crawlingrobotfortress.blogspot.com discuss about ways to optimize 3D rendering on ILI9341 LCD and Arduino: Both optimizing ILI9341 LCD drivers and rendering basic wireframe meshes have been done before. XarkLabs provides an optimized fork of Adafruit’s library. Youtube user electrodacus has also implementd an optimize driver for the ILI9341 communicating over SPI. Better 3D graphics on […]
DIY I2C LCD Display
https://www.electronics-lab.com/diy-i2c-lcd-display/
sspence @ instructables.com shows how to interface a character LCD using I2C and only two IO pins. The typical parallel LCD used with an Arduino (16×2 or 20×4) has 16 pins. Only 6 I/O pins are required on the Arduino, but what if you could get that down to two I/O pins, and still have those […]
