Rotary Encoder with Arduino and Nokia 5110 LCD Tutorial
https://www.electronics-lab.com/rotary-encoder-arduino-nokia-5110-lcd-tutorial/
Today we will take a look at using a rotary encoder with Arduino and displaying rotation data on the Nokia 5110 LCD display. A rotary encoder is an Electro-mechanical device that converts angular position or the rotation of a shaft into analog or digital values. By turning the shaft to the right or left, we […]

COLIBRÌ: the driver for RGBW LEDs
https://www.electronics-lab.com/colibri-driver-rgbw-leds/
Boris Landoni @ open-electronics.org designed COLIBRI, a board able to drive 4 color LEDs. He writes: Recently some multicoloured power LEDs have appeared on the market and, differently from the more common RGB LEDs, they incorporate a white LED, as an addition: they are named RGBW (Red, Green, Blue, White) just because of this. They […]
Arduino controlled Dual Mono AK4490 DAC (Part 1)
https://www.electronics-lab.com/arduino-controlled-dual-mono-ak4490-dac-part-1/
This article is the first of a series detailing the design and build process of an Arduino controlled Dual Mono AK4490 DAC by DimDim: The design goal was to do a dual mono design so as to maximize SNR and channel separation. A 4-layer PCB design was chosen so as to have a very solid, low […]
