In case you haven’t performed with LED filament (typically referred to as LED noodles) it’s a fascinating LED materials. It’s typically used industrially within the manufacture of retro or vintage-looking incandescent-style LED lamps, however it’s also now obtainable from maker suppliers in quite a few colors and lengths. It presents a large benefit over issues like EL wire in that it’s comparatively brilliant and simply seen in daylight. Utilizing small 18.5mm 3V LED filaments the InfiDig is an assembled board aiming to make 7-segment shows extra visually fascinating and provides your initiatives some aptitude!
The InfiDig on provide is listed as a Beta. It has a few bodge wires added to the pre-assembled PCB to make it operational. That mentioned, it’s a price range worth and comes fully assembled. The LED filaments are addressed by easy shift registers so it’s fairly trivial to animate and likewise simple to chain modules collectively. It’s able to displaying values between -199 and +199. You’ll want a 3.3-5V provide able to delivering as much as 350mA per InfiDig module. There’s a easy PWM management for brightness on board and a customized PlatfromIO library. This makes it a breeze to arrange an SPI interface on your microcontroller of alternative.
It may be value trying right into a diffuser to position in entrance of the shows. This may typically paradoxically make diffuse mild sources simpler to learn, a tip we picked up from Mike Harrison of mikeselectricstuff!
