LED Weather Forecast using Raspberry Pi
https://www.electronics-lab.com/led-weather-forecast-using/
AughtNaughtZero @ instructables.com posted his latest project, a LED matrix visualizing data from a weather website such as temperature, pressure, humidity, wind speed etc. This project utilizes a 6 x 16 matrix of RGB LEDs to visualize a weather forecast pulled from the Weather Underground API. A Raspberry Pi runs a python program designed to fetch […]
DIY Morning Feed With LED Matrix
https://www.electronics-lab.com/diy-morning-feed-led-matrix/
Here is a LED matrix able to show useful information such as weather forecast, temperature and stock updates. The matrix is controlled by a Particle Photon board. You wake up in the morning. You’re groggy. You grab your phone lazily and start browsing. You check the weather, your stocks, your instagram. Before you know it, you’re […]

LT8391 – 60V Synchronous 4-Switch Buck-Boost LED Controller
https://www.electronics-lab.com/lt8391-60v-synchronous-4-switch-buck-boost-led-controller/
The LT8391 is a synchronous 4-switch buck-boost LED controller that regulates LED current from input voltage above, below, or equal to the output voltage. The proprietary peak-buck peak-boost current mode control scheme allows adjustable and synchronizable 150kHz to 650kHz fixed frequency operation, or internal ±15% triangle spread spectrum operation for low EMI. With 4V to […]
RGB LED Strip Controller
https://www.electronics-lab.com/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 […]
A biometric sensor for wearables – LG Innotek
https://www.electronics-lab.com/a-biometric-sensor-for-wearables/
LG Innotek has released an ultra-thin optical biometric sensor module designed to be used in wearables and smartphones to measure health parameters such as heartbeat, stress indicators and blood oxygen saturation level. The new sensor is more accurate than it’s predecessors achieving ±5 bpm range of error and consumes very little power to operate. At stable heartbeat […]

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 […]
Controlling Arduino using your Voice
https://www.electronics-lab.com/controlling-arduino-by-voice/
bluehybrid @ instructables.com shows us how to use your voice to control a led light on Arduino. To achieve this he used the 1Sheeld Arduino shield. This Project is getting start to use arduino with 1Sheeld In this project we will turn an LED (ON) and turn it (OFF) by Voice We will say “Open” to turn […]
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 […]
