Color sensor achieves high dynamic range with auto exposure
https://www.electronics-lab.com/color-sensor-achieves-high-dynamic-range-auto-exposure/
Massimo Gottardi@ edn.com writes: The Design Idea in Figure 1 is a color detector capable of generating an RGB triplet over a high dynamic range, a useful attribute for machine vision applications. The circuit implements auto-exposure control to achieve this. Thus, RGB values for a subject are invariant over a range of light intensity. Color […]
16×32 RGB Matrix Panel Driver Arduino Shield
https://www.electronics-lab.com/16x32-rgb-matrix-panel-driver-arduino-shield/
Raj @ embedded-lab.com has revised his RGB Matrix Display Shield to an improved version. The shield now also carries the DS1307 RTC chip on board along with a CR1220 coin cell battery holder on the back. It is applicable for driving popular 16×32 RGB matrix panels with HUB75 (8×2 IDC) connectors. Row and column driver circuits are […]
Arduino Proximity Alarm
https://www.electronics-lab.com/arduino-proximity-alarm/
Lucas Reed @ instructables.com has build a proximity alarm using Arduino and an ultrasonic sensor from Parallax. If a nearby object is approaching then the alarm will sound and an RGB LED will light up. He writes: An ultrasonic rangefinder and Arduino microcontroller will check for nearby objects and if need be, alert you with […]

In this project, you’re going to build a web server with an ESP8266 to remotely control an RGB LED. This project is called ESP8266 RGB Color Picker. ESP8266 RGB Color Picker – [Link]
DIY Arduino RGB LED Controller Shield
https://www.electronics-lab.com/diy-arduino-rgb-led-controller-shield/
One of our visitors tipped us with his latest project, an Arduino RGB LED controller using low Rds-on MOSFETS, designed in Solo-PCB. This Arduino shield is designed to drive RGB (Red Green Blue) LED strips by using PWM (Pulse Width Modulation) method. It can brighten up and down each color independently by changing the duty […]
RGB LED Strip Controller

Thomas Gonnot has published a RGB LED Strip Controller based on STM32F0 microcontroller. The controller is able to power NeoPixel and DotStar protocol RGB LEDs. A simple controller for a RGB LED strip, with independent control of color and intensity. The design is based on a simple STM32F0 microcontroller. It can handle NeoPixel and DotStar […]
SK6812 – a new intelligent RGB LED
https://www.electronics-lab.com/sk6812-a-new-intelligent-rgb-led/
Tim discuss about a new RGB LED that appeared on the market: During the last months, a new WS2812 alternative appeared on the market: The SK6812. I finally managed to get my hands on some of them to take a closer look. In most aspects these devices are basically clones of the WS2812. What is […]
PWM dimmer for RGB LED
https://www.electronics-lab.com/pwm-dimmer-for-rgb-led/
Lukas Fassler has designed and built a PWM dimmer for RGB LED: In my last post I’ve described the design and construction of my LED dimmer project. This project here is similar but a bit more involved. It controls RGB LEDs so it can not only change the brightness but also the color of the […]
8×8 RGB Led Matrix with WS2812 driver with Arduino Uno
https://www.electronics-lab.com/8x8-rgb-led-matrix-with-ws2812-driver-with-arduino-uno/
In this video we learn how to use this 8×8 RGB LED matrix. This matrix is using the WS2812 driver and it is great, because each LED is individually addressable. Only one microcontroller pin is required to control all the LEDs, and you get 24 bit color for each LED. 8×8 RGB Led Matrix with […]
