Drive WS2812B LED strips from a PMOD device, a lightdriver project @ anfractuosity.com: I created a PMOD module PCB using KiCAD, that enables connecting WS2812B lighting strips to an FPGA board with a PMOD interface. The board was assembled by JLCPCB. This is my first project using an FPGA, I plan to soon implement an […]

3 cent PMS150C MCU driving 300 WS2812B LED’s
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 lot of RAM (64 bytes) […]
An Arduino Knight Rider Rainbow dice that uses WS2812B RGB LEDs
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 using the Arduino framework, because […]
SXAM: A Spark.io indoor ambient quality monitor
Davide Gironi published a new build, a Spark.io indoor ambient quality monitor: SXAM (Spark to Xively AMbient quality monitor), is an ambient quality monitor that logs 4 environmental parameters to the xively.com and display the ambient status by using for RGB leds. SXAM logs: Humidity Temperature Ambient noise Brightness Project info at Davide’s blog. Check […]
LED logger v3
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 are 16 light channels, 15 […]
APA102 aka “Superled”
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 wasteful, but it has the […]
