3 cent PMS150C MCU driving 300 WS2812B LED’s

Tuesday, June 25th, 2019

Driving 300 WS2812B RGB LED's with "the 3 cent microcontroller" - the Padauk PMS150C. The 3 cent Padauk PMS150C is.. Interesting to say the least. First of all there’s a lot this little MCU doesn’t do. It doesn’t have a lot of code space (1K Word), it doesn’t have a...

An Arduino Knight Rider Rainbow dice that uses WS2812B RGB LEDs

Thursday, March 2nd, 2017

An Arduino Knight Rider Rainbow dice built using a clock by Davide Gironi: This project implements a Knight Rider / Rainbow effect Random Selector. It uses an Arduino UNO and a WS2812B RGB led strip. A friend of mine needs a random selector for train scale model. I've developed this...

LED logger v3

Monday, March 16th, 2015

Bogdan of Electro Bob built a LED logger v3, that is available on github: In short:  16 LED channels are measured, one is kept for control of the sensor. For each LED the power supply and current are measured. The temperature of the aluminium plate is measured as well. In total there...

APA102 aka “Superled”

Monday, September 22nd, 2014

cpldcpu writes: I contrast to the very timing-sensitive one-wire protocol of the WS2812, the APA102 uses a standard two wire SPI protocol – one clock line and one data line. Each LED has two inputs and two outputs which can be daisy chained. At the first sight this may seem...
